Homework Answers
1)
Sn is metal
S is non metal
Si is metalloid
F is non metal.
Sn is only metal and hence it will be most metallic
Answer: a
2)
a)
C is larger than O.
Because both are present in same period and metallic radius decreases as we move from left to right in a period
Answer: C
b)
Rb is larger than Na.
Because both are present in same group and metallic radius increases as we move down a group.
Answer: Rb
C)
Al is larger than C
Because atomic radius decreases as we move diagonally from bottom left to top right
Answer: Al
D)
Se is larger than F.
Because atomic radius decreases as we move diagonally from bottom left to top right
Answer: Se
