IONIC BONDING
WHAT MAKES A ATOM REACTIVE
NOT HAVING A COMPLETE OUTER SHELL
COVALENT BONDING
THEY SHARE ELECTRON
the equation for density
What is d = m/v? (mass divided by volume)
these measurements are very close to one another but not near the actual value.
What is precise but not accurate?
You always need to do this when taking a measurement.
What is estimate one digit?
WHAT HAPPENS IN AN IONIC BOND
AN ATOM EITHER GAINS OR LOSES AN ELETRON
HOW ELEMENTS ARE HELD TOGETHER IN COVALENT BONDING
BECAUSE THEY ARE SHARING ELECTRONS
