The Periodic table of elements is a tool, developed by scientists over hundreds of years. The table lists all the elements that are currently known, in descending order of the number of protons that are present in a single atom of the element.

You can download and print the pdf file of the printable periodic table of the elements. This periodic table gives the electronegativity value for each of the elements. Valence is a measure of how many chemical bonds can be formed by an element. The IUPAC defines valence to be the maximum number of univalent atoms such as hydrogen or chlorine atoms that may combine with an atom of the element.

Keep in mind, the valence is the maximum number of bonds, not the usual number of bonds. Know elements contain the same number of electrons as protons. There is an exception if they're ionized. Protons have a positive charge, and electrons have a negative charge. However, an atom can lose or gain electrons, which makes it ionized.

If it has more electrons, the ion is negative, which is indicated with a negative symbol. You will not see a plus or minus symbol if the element is not an ion. Part 3. Find the atomic weight. The atomic weight usually appears at the bottom of the box, below the element symbol.

The atomic weight represents the combined weight of the particles in the nucleus, which includes protons and neutrons.

However, ions complicate the calculation, so the atomic weight represents an average of the atomic mass of the element and the atomic mass of its ions. Although it may appear as though the atomic weight increases in number from top left to bottom right, this is not true in all cases. You can find the mass number by rounding the atomic mass to the nearest whole number.

This accounts for the fact that the atomic weight is an average of all possible atomic masses for that element, including ions. Similarly, the weight of Iron is Subtract the atomic number from the mass number to find the neutrons. The mass number is calculated by adding together the number of protons and neutrons. This allows you to easily find the number of neutrons in an atom by subtracting the number or protons from the mass number! Did you know you can get expert answers for this article?

It will be positively charged because the number of protons is now greater than the number of electrons.

Protons are positively charged, while electrons are negatively charged. Usually an atom has the same number of electrons as protons, but when there are more protons, the atom has an overall positive charge. Not Helpful 19 Helpful The atomic mass, given in atomic mass units amu , is generally very close to the atom's mass number. The mass number is found by adding the number of protons and neutrons in the atom. This number is based on Carbon, and as a result, Carbon has an atomic mass of However, other elements have decimal atomic masses, such as Hydrogen, which has a mass number of 1 but an atomic mass of 1.

Essentially, it is the total mass of the atom, electrons included. Elements with similar properties are arranged in the same column called a group , and elements with the same number of electron shells are arranged in the same row called a period. Elements are arranged in the periodic table based on their number of protons or atomic number.

Information Pooling : Ask the class to think of all the elements they know. Compile a list on an overhead projector transparency or the classroom chalk board as the students make suggestions. If some students suggest compounds such as water or air , clarify the difference between elements and compounds.

When no more suggestions are forthcoming, bring out the periodic table, and point out the locations of all the elements suggested by the students.

Pairs Check : After student teams create their superhero character from their element card, have them check with another group to verify that they have the correct information included in their design sketch. Engineering Design Presentations: Have each team present their design of an element superhero. Require the presentations to include: the name of the element, the element clues that were given, specifically how the element was identified, the chemical symbol, the atomic number, the name of the superhero, how the superhero's look relates to the element, how the superhero's powers relate to the element, the audience for the character, and how they designed it for that audience, and a drawing of the superhero.

Human Periodic Table : Ask students to clear an area in the classroom move desks aside or go outside and arrange themselves like the common periodic table. As time permits, go around as they are arranged and ask them to explain the logic of their element position in the table, using what they learned during the activity.

At the end of the activity, in their class presentation or while they are describing their position in the Human Periodic Table see Assessment section , have teams share this fact with the class. Complete the Table : Make a full superhero periodic table by assigning the rest of the elements to the students. Have them research the elements enough to design a superhero with similar characteristics. Then hang these on the wall with the original 20 element superheroes.

Why Teach Engineering in K? Find more at TeachEngineering. Quick Look. It's either find a copy of the periodic table, or memorize one. Most chemistry textbooks have a periodic table printed on the inside cover. Find the element you're studying. Most periodic tables include the full name of the elements, as well as the chemical symbol such as Hg for Mercury. If you're having trouble finding it, search online for "chemical symbol" followed by the name of the element.

Look for the atomic number. The atomic number is usually in the top left or top right corner of the element's box, but it could be in a different spot. This is always a whole number. If the number includes a decimal point, you're probably looking at atomic mass instead. Confirm based on nearby elements. The periodic table is arranged in order of atomic number.

If your element's atomic number is "33," the element to the left should be "32" and the element to the right should have a " You may see gaps after elements 56 Barium and 88 Radium. There's no actual gap; the elements with those atomic numbers are located in two rows below the rest of the chart. They are only separated like this to fit the periodic table in a more narrow shape.

Understand atomic number. An element's atomic number has a simple definition: the number of protons in one atom of that element. The number of protons determines the total electric charge of the nucleus, which determines how many electrons the atom can support.

Because electrons are responsible for almost all chemical interactions, the atomic number indirectly sets almost all of the element's physical and chemical properties.

To put it another way, every atom with eight protons is an oxygen atom. Two oxygen atoms might have different numbers of neutrons or if one is an ion different numbers of electrons, but they will always have eight protons each.

Part 2. Find the atomic weight. The atomic weight is typically printed below the element name on the periodic table, usually to two or three decimal places. This is the average mass of one atom of the element, weighted to what you would expect to find in nature. This number is in "atomic mass units" AMU.
