Question | Answer |
---|---|
when does the 1st element get a prefix | if it has more than 1 of itself |
where does the atomic radius increase? | left and down |
shielding | inner electrons block the nuclear charge toward the outer shell electrons |
electronegativity | the atom's ability to pull an electron towards itself when bonded (getting smaller?) |
do big atoms have lots or not that much electronegativity? | not that much, since the electrons would be spread out thus taking up more space |
in what direction in the p-table does electronegativity increase | up and to the right |
ionization energy | the amount of energy needed to pull an electron off |
in what direction in the p-table does ionization energy increase | up and to the right |
1st ionization energy | the amount of energy needed to remove the 1st electron |
2nd ionization energy | the amount of energy needed to remove a 2nd electron |
trends in atomic radius | radius increases as you go left and down |
for what type of bonding do you use prefixes | nonmetal+nonmetal |
do you include charges of elements in ionic or covalent bonding | ionic bonding |
