general overview not great but still print it of

?
describe an atoms structure
neutrons(neutral)+proton(positive) and electrons in the outer shell(negative)
1 of 18
explain the different states of matter
SOLID=vibrate on the spot with a regular pattern and close togetherLIQUID=move around each other and close together in a random arrangementGAS=move quickly in all directions which are far apart and a random arrangement
2 of 18
how do you find RFM
you add the relative atomic mass values for all the atoms in the formula
3 of 18
what is a mole's volume
24dm3 of 24,000 cm3 all at room temp and pressure
4 of 18
what is an ionic bond
a chemical bond formed between two ions with opposite charges. they form when one atom gives up one or more electrons to another atom
5 of 18
how are simple molecular substances bonded and what are the boiling points
they consist of molecules in which the atoms are joined by weak covalent bonds and they have low melting points and do NOT conduct electricity
6 of 18
describe giant covalent structures
many atoms covalently bonded molecules to form a giant lattice. They have high melting points
7 of 18
what makes a good conductor of heat and electricity
metals because they form giant structures containing free electrons
8 of 18
what are covalent bonds and what two types are there
covalent bonds form between non-metal atoms. Each consist of a shared pair of electrons and is very strong. there is two types SIMPLE MOLECULES and GIANT COVALENT STRUCTURES
9 of 18
what are simple molecules
diagram of carbon dioxide
10 of 18
what are the properties of simple molecular substances
low melting and boiling points because intermolecular forces are broken easily and NON CONDUCTIVE they do not conduct electricity because there is no free electrons or an overall electric charge
11 of 18
what is metallic bonding and what is it's properties
metals form giant structures in which electrons in the outer shell of the metal atoms are free to move. The metallic bond is a force of attraction between free electrons and metal ions. PROPERTIES high boiling points, conductors of electricity+heat
12 of 18
what is electrolysis
ELECTROLYSIS is the process by which ionic substances are decomposed into simpler substances when an electric current is passed through them
13 of 18
describe electrolysis
diagram of electrolysis
14 of 18
how does electrolysis work
1ions must be free to move2ions are free to move when an ionic substance is dissolved in water or when melted
15 of 18
what is an example f electrolysis
if electricity is passed through MOLTEN lead bromide, the lead bromide is broken down into lead and bromine
16 of 18
what happens during electrolysis
POSITIVELY charged ions move to the negative electrode during electrolysis. they receive ELECTRONS and are REDUCED negatively charged ions move to the positive electrode. They lose electrons and are OXIDISED
17 of 18
what is the substance called after electrolysis happens
an electrolyte
