how does the sheilding effect work

the sheilding increases bc there there is an increase in the # of shells

amount of energy required to detach one electron

atomic size increases going down a group

across the periodic tabel

atomic size decreases going across a period [L-R]

the distance between the center of the nucleus and the outermost shell

Sheilding Effect meaning

Inner electron block outer electrons from attraction to the nucleus

half the distance between two ions that are barely touching each other

energy required to remove an electron

1
across the periodic table the nuclear charge gets stronger
False
True
2
how does the sheilding effect work
the sheilding increases bc there is a decrease in the # of shells
the sheilding decreases since there is a decrese in # of shells
the sheilding decreases bc there is a decrease in the # of shells
the sheilding increases bc there there is an increase in the # of shells
3
an increase in nuclear charege increases the pull on an atom outermost electrons
False
True
4
cations are positive and lose an electron so the get smaller
True
False
5
electron affinity
amount of energy required to detach one electron
half the distance between two ions that are barely touching each other
the distance between the center of the nucleus and the outermost shell
measure of the size of an atom
6
atomic radii
atomic size decreases going across a period
atomic size decreases going down a group
atomic size increases going down a group
atomic size increases goining across a period
7
electronagitivity trend is the ability to attract outside electrons in a bond
True
False
8
ionization energy increases left to right on the periodic table [nucleus gets stronger making it harder to steal]
True
False
9
across the periodic tabel
atomic size increases going across a period [L-R]
atomic size decreases going across a period [L-R]
10
atomic size
measure of the size of an atom
amount of energy required to detach one electron
the distance between the center of the nucleus and the outermost shell
half the distance between two ions that are barely touching each other
11
nuclear charge
# of Electrons
# of protons
# of Nutrons
12
Sheilding Effect meaning
Inner electrons release electrons
inner electron block protons from attraction to the nucleus
inner electrons allow electrons to attract to the nucleus
Inner electron block outer electrons from attraction to the nucleus
13
Atomic Radius
amount of energy required to detach one electron
the distance between the center of the nucleus and the outermost shell
half the distance between two ions that are barely touching each other
measure of the size of an atom
14
Atoms of metallic elements tend to lose an electrons and form positive ionsIonization energy
False
True
15
Ionic Radius
the distance between the center of the nucleus and the outermost shell
amount of energy required to detach one electron
measure of the size of an atom
half the distance between two ions that are barely touching each other
16
Anions are negative and gain an electron and get bigger
True
False
17
ionization energy decreases top to bottom on the periodic table [more shells having a weaker nucleus easy to steal]
False
True
18
Ionization energy
energy required to gain an electron
energy required to remove an electron
19
across a period the principle energy level remains the same so sheilding remains constant
True
False
