Structure and bonding T2

Question 1

What are ions?

Answer 1

Ions are charged particles - they can be single atoms or a group or a group of atoms

Question 2

What is another name for negative ions and what are they?

Answer 2

Negative ions (also known as anions) form when atoms gain electrons - they have more electrons than protons

Question 3

What is another name for positive ions and what are they?

Answer 3

Positive ions (also known as cations) for when atoms lose electrons - they have more protons than electrons

Question 4

Why are group 1 and group 2 elements most likely to form ions?

Answer 4

Because they will lose elcetrons

Question 5

What is the overall charge of an ionic compound?

Answer 5

Zero

Question 6

What happens when a metal and non metal react together?

Answer 6

The metal atom loses electrons to form a positive ion, and the non - metal gains these electrons

Question 7

What do features do ionic compounds have?

Answer 7

Ionic compounds have high melting and boiling points due to strong atttraction

Question 8

What is a covalent bond?

Answer 8

A covalent bond is a strong bond that forms when a pair of electrons is shared between 2 atoms
