Question

3.3 how do metals and non metals react​

Answer 1

Answer:

Metal atoms have only a few electrons in their outer shell whereas non-metal atoms have lots of electrons in their outer shell. This means that metals tend to react with non-metals. When a metal reacts with a non-metal, electrons transfer from the metal to the non-metal.

Answer 2

Answer:

Metal atoms have only a few electrons in their outer shell whereas non-metal atoms have lots of electrons in their outer shell. This means that metals tend to react with non-metals. When a metal reacts with a non-metal, electrons transfer from the metal to the non-metal. This creates oppositely charged ions:

metal atoms lose electrons to form positive ions (cations)

non-metal atoms gain electrons to form negative ions (anions)

Example - sodium chloride

When sodium reacts with chlorine, one electron is transferred from the sodium atom to the chlorine atom. This creates a positive sodium ion and a negative chloride ion.
