Poll

What happens if you remove a proton from an atom?

• Loses atomic mass and change the element

• Becomes more positive

• Becomes more neutral

Multiple Choice

If an atom gains 2 electrons, what is its charge?

• Negative(-)

• Positive(+)

• Neutral(0)

Multiple Choice

If an atom loses 3 electrons, what is its charge?

• Positive(+)

• Neutral(0)

• Negative (-)

Open Ended

Calculate the charge and identify the ion: Sodium (Na) with 10 electrons

Open Ended

Calculate the number of electrons and identify the ion: Boron +3

Ions vs Isotopes

Ions=different number of electrons only

affects charge

Isotopes=different number of neutrons only

affects atomic mass
