Q-2
Answer B
They share the same atoms in common.
Q-7
Answer C
One atom moved into the valance electrons. In the ground state, the configuration would be 2-6.

Q- 20
Answer- (B)
because has an odd number of molecules
Q-14
Answer- (C)
because on Periodic Table of the Elements, the elements are organized by the the atomic number
Q- 17
Answer- (A)
because aluminum, argon and antimony are elements
Q- 19
Answer- (B)
because ionic has to deal with  transferring bonds and molecular is a form of covalent where electrons are shared with atoms

3.B
Oxygen has higher electro-negativity than sulfur
4.B
entropy is important as it describes the form and distribution of energy. for a process to occur spontaniously, its a needed condition that the entropy of the system undergoing the process to increase.
6.A
electrons have a charge of -1 and protons have a charge of 1, there is one more proton that electrons.
8.C
Ca has the lowest melting point out pf all of the options
9.A
when a positive and negative with no numbers at the end, they can "just combine"
10.D
because the equation shows reactants combining to make 1 product that contains the same molocules.
11.
12.A
because the difference in elctronegativity is the smallest between hydrogen and iodine compared to other bonds
13.
15.B
this allows each molocule of X2 to attach evenly to each molocule of Z2
19.
20.c
the electron is negativley charged and is not in the nucleus
