Elements and Chemistry Exam Questions?

Question

3 Questions:

1. Identify general features of the periodic table (e.g. arrangement of the elements based on atomic structure, groups or families of elements, periods or horizontal rows)

2. Relate the Bohr-Rutherford atomic model to properties of elements and their positions in the periodic table

3. Compare similarities in properties both between and within families of elements to similarities in their atomic structure (e.g. alkali metals, halogens, noble gases).

Most important are 2 and 3
Thanks!

Answer 1

Columns are called groups or families and have the same out level valence electron arrangement. This means they have similar characteristics.

Rows are called periods or series. They have the same number of electron levels.

Properties of boiling point, electronegativity, ionic radius, atomic radius, density, etc. can be determined by the location of the element on the table.
