IMPORTANT NOTE!!! When you see “organic” think CARBON!*Organic = carbon

Atom Structure*

Center of an atom called… ? Made of…?

Nucleus contains protons and neutrons

Protons (+1)

Neutrons (0)

Electrons (-1)

The atom Ca is neutral (# protons = # electrons), where as Ca +2 has 2 extra protons than electrons

Electron Shells*The “ring” of electrons around the nucleus are called electron shells

1st shell: Max of 2 electrons

2nd shell: Max of 8 electrons (ideal)

The arrangement of electronsallows atoms to bondtogether

Which one of these atoms is most likely to lose an electron?

When bonds are made, energy is released (ex.

Explosion)*

MCAS Question

Be able to EXPLAIN your answer!!

Abundant = when a substance is present in high quantities
