1
The Atom Nucleus center of atom. contains neutrons contains protons Neutrons neutral charge N 0 1.67 x 10 -27 mass in the nucleus
2
Protons Positive charge P + 1.67 x 10 -27 Mass Found in the nucleus Electrons Negative charge e- 9.11 x 10 -31 Mass Found outside nucleus in energy levels /shells in a specific orbital
3
Electrons can be found in 1 of 4 shells 1 st shell holds 2 electrons 2 nd shell holds 8 electrons 3 rd shell holds 18 electrons 4 th shell holds 32 electrons
4
Electrons can be found in 1 of 4 orbitals in the shells S,p,d or f S orbital lowest level 2 electrons sphere shape
5
P orbital Holds 6 electrons dumbell shape xyz D orbitalholds 10 electrons F orbital holds up to 14 electrons and is the highest energy level
6
The last shell electrons are found in;is called the valence shell valence electronsThese electrons are then called the valence electrons and they are what determine if the atom will bond with anything else or not.
7
The Atom All atoms are neutral so … Protons which are positive must equal electrons which are negative ( cancel each other out) WKRP Atom Explanition
