17
Q

What are the classifications of the elements

A
  • **S BLOCK ** 1-2
  • **P BLOCK ** 13-18
  • D BLOCK TRANSITION METALS

Q

Define the atomic Radius

A

The radius of the size of the atom, from nucleus to outermost electron,
left —–> right

19
Q

Describe the rate of Ionization energy and electronegativity as the atomic radius increases and decreases

A

As atomic radius decreases (left -> right)
Ionic Energy increases
electronegativity increases
As atomic radius increases (top -> bottom)
ionic energy decreases
electronegativity decreases

20
Q

Ionization energy is how strong..

A

the nucleus holds onto its outermost electrons

21
Q

Electronegativity indicates the…

A

relative ability to attract electrons in a chemical bond

22
Q

What is the direction of increasing electronegativity

A

up and right

23
Q

all elemnts in group one are metals except..

A
