Metallic Bond

Loses electron

Metallic Bond

Always positive

Metallic Bond

Opaque and reflective

Metallic Bond

Conductive and malleable

Metallic Bond

High Melting Point

Ionic Bond

Stronger than a metallic bond

Ionic Bond

Salt

Ionic Bond

Perfectly transferred, one electron lost, one gained

Ionic Bond

Widely spaced, electromagnetic force

Ionic Bond

Transparent, non conduction unless bond is brooken

Ionic Bond

brittle

Ionic Bond

Extremely high melting point

Ionic Bond

Metal with Nonmetal

Covalent

Nonmetal with Nonmetal

Covalent

Molecule

Covalent

Shared electrons on bonds but exist individually

Covalent

Transparent and nonconductive

Covalent

Brittle in solid form (Ice)

Covalent

low melting point

Dipole - Dipole

Intermolecular force that is polar

Hydrogen Bonding

Can be bound with F, O, N. Extremely strong form of a dipole-dipole bond

Dispersion Force

Non Polar molecules, holds together a non polar molecule

Noble Gases

Never react or bond

Non Polar Test

1. Bound to itself H2, N2, F2, O2, I2, Cl2, Br2
2. Straight or symmetric
3. Carbon chain

Silicate: Filament

asbestos, stringy

Silicate: Framework

no weak spot, built in triangles, quartz

Silicate: Sheet

Bonded on top, not on bottom, mica

Unsaturated Fats

Fats that are kinked at the doublebond, good for you, and cannot stack

Saturated Fats

Straight, begin to stack, are OK for you

Trans Fats

Bad for you, man made, hydrogenated oil, highest melting point so your body has to work hardest to get rid of them. Straight and double bonded

Semiconductor

Cant decide if metal or nonmetal. Works better as it gets hotter. Band gap gets closer as it heats up, using less energy to work. Change in temperature creates different resistance and different color. Blue light

Alpha Decay

Large elements decaying, release of helium nucles (alpha particle) as the decay occurs

Beta Decay

Carbon 14, all elements can go through this decay. Neutron becomes a proton

Gamma Decay

You lose a gamma ray, but nothing changes with the atom.

Iron

at the bottom of the nuclear reaction chart because it is the most stable element. Fe

Fusion

The growth in atomic mass by combining two atoms, gives off nuclear energy

Fission

The loss of mass in the atom gives of energy
