Chemistry

Question 1

Trend for Electronegativity

Answer 1

From left to right across a period of elements, electronegativity increases

From top to bottom down a group, electronegativity decreases

Question 2

Trend for Ionization Energy

Answer 2

The ionization energy of the elements within a period generally increases from left to right

The ionization energy of the elements within a group generally decreases from top to bottom.

The noble gases possess very high ionization energies

Question 3

Trend for Atomic Radius

Answer 3

Atomic radius decreases from left to right within a period

Atomic radius increases from top to bottom within a group

Question 4

Trend for Melting Point

Answer 4

Metals generally possess a high melting point

Most non-metals possess low melting points

Question 5

Trend for Metallic Character

Answer 5

Metallic characteristics decrease from left to right across a period

Metallic characteristics increase down a group
