101 .
I II
The most important factor in determining the chemical
properties of an element is the number of electrons in the
outermost shell
BECAUSE the number of electrons in the outer
shell determines the bonding
characteristics of the element.
102 .
I II
NH 3 is a Lewis base BECAUSE it can accept a proton.
103 .
I II
An element (X) with an atomic number of 16 has 14 electrons
in X2−
BECAUSE two protons bind the two outermost
electrons.
104 .
I II
Bromine is a stronger oxidizing agent than chlorine BECAUSE it has a large atomic radius.
105 .
I II
An exothermic reaction has a positive ΔH BECAUSE heat must be added to the system for the reaction to occur.
