Physical Science Exam 3

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
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
Ionic Bond
Extremely high melting point
Ionic Bond
Metal with Nonmetal
Nonmetal with Nonmetal
Shared electrons on bonds but exist individually
Transparent and nonconductive
Brittle in solid form (Ice)
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
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.
at the bottom of the nuclear reaction chart because it is the most stable element. Fe
The growth in atomic mass by combining two atoms, gives off nuclear energy
The loss of mass in the atom gives of energy
