Answer:
8
Explanation:
since neutron number is A-Z and mass number is 14 minus Atomic number 6
B. because if you add ice to tea and water it decreases the temperature as the ice melts
Explanation:
A. Hydrogen bonding is present in CS2 but not in CO2.
B. CS2 has greater dipole moment than CO2 and thus the dipole-dipole forces in CS2 are stronger.
C. CS2 partly dissociates to form ions and CO2 does not. Therefore, ion-dipole interactions are present in CS2 but not in CO2.
D. The dispersion forces are greater in CS2 than in CO2.

Answer:
D. a magnesium ion
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 12 protons than it must have 12 electrons.
In given question there are 12 protons and 10 electrons which means the neutral atom loses 2 of its valance electrons and form ion.
It is magnesium atom because mass of given atom is
Number of proton+ number of electron = 12+12 = 24 amu
and atomic number is 12.
Alpha radiation results in the greatest change of atomic number,
since 2 protons are removed from the nucleus to emit 1 α particle.
