Does electronegativity increase or decrease on the periodic table?

A

It increases from left to right

37

What is atomic radius?

A

The size of the atom

39
Q

How does atomic radius decrease on the periodic table?

A

Decreases from left to right

40
Q

How does electrostatic charge affect atomic radius?

A

The bigger the atomic number, the smaller the atomic radius because the electrostatic charge. It makes the electrons and protons more attracted thus pulled together.

41

How do you find the identity of an element?

A

The number of protons

42
Q

What determines reactivity?

A

The number of valence electrons

43
