Summary

this document has three different graphs which are of the three periodic trends in the first 36 elements of the periodic table. We also had to answer some questions...

Atomic Number

Part 1: Atomic Radius

1. 2. 3. 4. 5. 6.

It’s half of the distance between 2 nuclei of a diatomic molecule Li, Be, B, C, N, O, F, Ne. Their radius values drop as you move across the table. Periods 3 and 4 have the same trends The radiuses increase Yes; going down the group they also increase. Decreases, increases.

Atomic Number

Part 2: Ionization energy

1. The amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation. The KJ/mol unit means how many KJ of energy are required to remove one mol of electrons from 1 mole of gaseous atoms. 2. Overall, it increases. The Ionization energy increased. 3. Yes; They both increase overall. 4. Ionization energy decreases moving down a group. 5. Yes. 6. Increases, decreases.

Atomic Number

1. The tendency of an atom to attract electrons to > when chemically combined with another element 2. It increases as we move across the period and doesn’t existent at 10. 3. Yes, overall their electronegativity increases. However, in period 4 it’s slower and at some points it decreases. 4. It decreases. 5. It also decreases. 6. Since they are noble gasses, they have full valence shells and normally cannot attract other electrons. 7. Increases, Decreases....
