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
