Answer 3

Atomic Number

Question 4

Vertical collumns in periodic table are called…?

Answer 4

Groups

Question 5

Horizontal rows in periodic table are called…?

Answer 5

Periods

Question 6

Elements in the same period have?

Answer 6

Same number of shells (major energy levels)

Question 7

Elements in the same group have?

Answer 7

Same number of valence electrons

Question 8

Why do elements in the same group have the most similar properties?

Answer 8

Becasue they have
* Same number of valence electrons
* and same outer shell electron configuration
* thus interact with other substances similarly
