Group 1 Metals

Question 1

What are group one metals also known as?

Answer 1

Alkali metals

Question 2

What properties do all of the group one metals have?

Answer 2

Low melting points
Low density
Very soft

Question 3

What is the difference between covalent and ionic bonds?

Answer 3

Covalent are formed when two atoms share electrons, while ionic compound is when an electron is given to another element

Question 4

What compounds do alkali metals form?

Ionic

Question 5

Why don’t alkali metals form covalent bonds?

Answer 5

They loose their one outer electron so easily that sharing it would be out of the question

Question 6

As you go down the group one elements, they get less reactive. Why is this?

Answer 6

The further down, the more shells they have, this means the electrons are further away from the nucleus so it’s less strongly attracted

Question 7

Answer 7

The react vigorously
