Answers
1
elements in the same period have
no similar properties
the same # of occupied energy level(s)
similar properties
2
who organized the elements by increasing atomic mass
Moseley
Mendeleev
3
atomic size
increase as you move right/ decrease as you move down
increase as you move down/ decrease as you move left
4
IE and EN
are different
both decreases down, increase across
5
elements in the same group have
similar properties
same # of occupied energy level(s)
no similar properties
6
cations
-
+
7
verticle columns
group (families)
period (series)
8
the more electrons lost...
the smaller the ion becomes
the larger the ion becomes
9
metalloids
right of staircase, non-lustrous, brittle, poor conductors
touch the staircase and have nonmetal & metal properties
left of staircase, lustrous, malleable, ductile, conductors
10
nonmetals
left of staircase, lustrous, malleable, ductile, conductors
touch the staircase and have nonmetal & metal properties
right of staircase, non-lustrous, brittle, poor conductors
11
the inner electrons ___ or block the attraction from the nucleus (shielding effect)
absorb
shield
repel
12
d block
transition metals
intertransitional metals
representative elements
13
s and p blocks
transition metals
intertransitional metals
reperesentative elements
14
f block
transition metals
intertransitional metals
representative elements
15
anion
+
-
16
semiconductors
only conduct at high temperatures or chemical reactions
always conduct
never conduct
17
highest EN
Fr
Fl
18
ionization energy
the amount of energy required to remove an electron
the pull from the atoms to the nucleus
19
EN
decreases down, increases across
increases up, decreases across
20
atomic size
decreases right, increases up
decreases to the right, increases down
21
there is a very large increases of ionization energy whenever an electron is removed from atoms
that have very few electrons total
that are isoelectronic with a noble gas
22
1st IE
energy required to remove the 2nd electron
energy required to remove the 1st electron
23
the more electrons gained...
the smaller the ion becomes
the bigger the ion becomes
24
who organized the elements by increasing atomic number
Moseley
Mendeleev
25
metals
right of staircase, non-lustrous, brittle, poor conductors
left of staircase, lustrous, malleable, ductule, conductors
touch the staircase and have nonmetal & metal properties
26
IE
decreases down, increases across
increases up, decreases across
27
the periodic trend is less pronounced for periods further down the PT due to the
shielding effect
electronegativity
ionization
atomic size
28
horizontal rows
group (families)
period (series)
29
it takes more energy to remove
2nd or 3rd electron
1st electron
30
atomic size decreases as you move left to right BUT
the elements have a different # of energy levels
elements have the same # of energy levels (but more protons)
31
cations are ____ than the neutral atom from which they are made
larger
smaller
