Answers

1
The energy required to remove an electron from an atom is known as...
electronegativity
radioactivity
electron affinity
ionization energy
2
Which atom would have the largest radius?
nitrogen
boron
lithium
neon
3
What is the atomic radius of an atom?
the measurement of the electron
half the distance between 2 nuclei of identical atoms
distance that the electron travels
distance from the nucleus to the most outer valence electron
4
Which atom has the most electrons?
Na
Mg
Ca
K
5
Why does atomic radii decrease as you go from left to right across a period?
because there are more and more protons in the nucleus
because there are more electrons
because they are close to right side of the periodic table
because the outermost energy level can't hold more electrons
6
The tendency of an atom to pull an electron from another atom.
electron affinity
electronegativity
ionization energy
radioactivity
7
Why does atomic radius increase as you go down the periodic table?
number of energy levels decreases as you move down
energy level is too high
energy level is too low
number of energy levels increases as you move down
8
The elements with the largest ionization energy are found in the ...
lower left-hand corner of the periodic table
lower right-hand corner of the periodic table
upper right-hand corner of the periodic table
upper left-hand corner of the periodic table
9
A horizontal row ( → ) of elements on the periodic table may also be referred to as a ...
period
family
group
series
