Answer:
C. involve the attraction of opposite charges
Explanation:
<em>Ionic bonding</em> involves the attraction between <em>oppositely charged ions</em>, as in Na⁺ Cl⁻.
<em>Covalent bonding</em> involves the attraction between <em>negatively charged electrons and positivey charged nuclei</em>, as in a C-H bond.
A is <em>wrong</em>. Ionic bonding involves the transfer of electrons.
B is <em>wrong</em>. Covalent bonding involves the sharing of electrons.
D is <em>wrong</em>. Ionic bonds are usually stronger than covalent bonds.
<u><em>The variable quantities are expressed by the ideal gas law equation are; </em></u>

This question is simply based on defining the ideal gas law.
- Now, A gas is considered to ideal if its particles are so far from each other in such a manner that they don't exhibit any forces of attraction between themselves. Now, in real life this is not possible but under high temperatures and pressure, we can have something close to it and that's why ideal gas laws are very important.
- This law states that states that the pressure, temperature, number of moles and volume of a gas are related to each other by the formula;
PV = nRT
Where;
P is pressure
V is volume
n is number of moles
T is temperature
R is ideal gas constant (This is fixed and not variable)
The variable quantities are expressed by the ideal gas law equation are;
<em>pressure, volume, temperature, number of moles</em>

Answer:
28
Explanation:
electron = atomic number - charge(if the charge is positive and addition if the charge is negative)
electron = 30 - 2
electron = 28
