Which element has electrons in 3 energy levels, and is a semiconductor?
Ge
Si
Na
Mg
Which element has 6 valence electrons, is smaller than Se, and has a higher ionization than S?
Cl
P
As
O
Br
Which explains why K is more reactive than B?
Potassium is smaller and only has one valence electron that it loses easily.
Potassium has a higher ionization energy which is why is sparks when reacting with water.
Potassium is larger so it cannot hold on to its one valence electron easily, giving it a much lower ionization energy.
Boron is larger and has a higher ionization energy so it reacts more easily than K.
Which is correct?
Ca is more reactive than K because it is larger.
S is more reactive than Al because it has a higher ionization energy.
Cs is more reactive than K because it has a lower ionization energy and is larger.
Li is less reactive than Be because it has a higher ionization energy.
What is the relationship between an element's reactivity and its ionization energy?
Elements with a higher ionization energy are more reactive because the extra energy creates a stronger reaction.
Elements with a lower ionization energy are less reactive because the have less energy to give for reactions.
Elements with a lower ionization energy are more reactive because it is easier to lose an electron, causing a reaction.
