What is the name of the pictured isotope?

• Carbon-12
• Carbon-13
• Carbon-14
• Carbon-15

An atom with the same number of protons and electrons (no charge) and the expected atomic mass or number of neutrons from the periodic table.

• Neutral/Normal Atom

• Ion

• Isotope

An atom that has gained or lost electrons in an attempt to become stable/bond with another atom.

• Normal/Neutral Atom

• Ion

• Isotope

A negatively charged ion that has gained electrons to satisfy the octet rule (metals do this)

• Anion

• Cation

• Neutral Atom

• Isotope

A positively charged ion that has lost electrons to satisfy the octet rule (non-metals do this)

• Anion

• Cation

• Neutral Atom

• Isotope

Atoms of the same element that have different mass than expected because they have a different number of neutrons.

• Neutral Atom

• Ion

• Isotope

• Cation

If an ion has a positive charge you would __________ the charge number from the number of protons to figure out how many electrons there are.

• subtract

• add

• multiply

• divide
