1.4 Forming Bonds Flashcards
1
Q
What happens when different elements combine?
A
Compounds are formed
2
Q
What happens when a metal reacts with a non-metal?
A
Ions are formed
3

A
The metal atoms lose an electron and become positively charged. The non-metal atoms gain an electron and become negatively charged. The oppositely charged ions attract each other and the compound has ionic bonds.
4
Q
What does the chemical formula of an ionic compound tell us?
A
The simplest ratio of ions in the compound
5
Q
What happens when a non-metal reacts with a non-metal?
A
Their atoms share electrons to form covalent bonds and molecules are formed
6
Q
