Ions

The overall charge of an Atom is...

• Positive

• Negative

• Neutral

• Can be positive or negative

WHY are atoms overall charge always going to be neutral?

• The number of protons is more than the number or neutrons

• The number of protons is equal to the number of neutrons

• The number of protons is equal to the number of electrons

• The number of protons is less than the number of electrons

What is an Ion?

• An atom that now has a positive or negative charge

• An atom that experienced a mutation

• An atom that has less energy

• An atom that has more neutrons

How do ions form? (Select all that apply)

• If the atom gains protons

• If the atom loses protons

• If the atom loses electrons

• If the atom gains electrons

An ion that loses an electron will have an overall positive charge. This is called a(n)...

• Cation

• Anion

• Atom

• Positron

An ion that gains an electron will have an overall negative charge. This is called a(n)...

• Cation

• Anion

• Atom

• Positron

In order to form a positive cation, what must occur?

• The atom must lose a proton

• The atom must gain a proton

• The atom must lose an electron

• The atom must gain an electron

In order to form a negative anion, what must occur?

• The atom must lose a proton

• The atom must gain a proton

• The atom must lose an electron

• The atom must gain an electron

Ions can ONLY be formed if an atom gains or loses ELECTRONS! What happens if I change the number of protons in the nucleus of an atom?

• It will explode

• It will become unstable

• It is then considered a DIFFERENT element - atomic number provides identity

• It will become a compound

What TWO pieces of information can we learn from the atomic number? (Select all that apply)

• Number of protons in the nucleus

• Number of electrons in the cloud

• Number of neutrons in the nucleus

• The electron configuration in each orbital
