Answer:
Charge is caused by a flow of electrons, since electrons are around the nucleus they can be lost or gained by atoms. When an atom gets charged, it gains a charge, that is, it gains an electron. Since electrons are negatively charged, when an atom gains one, it also becomes negatively charged.
Answer:
17.92L or 17.92dm³1
Explanation:
number of moles of a gas = volume of that gas/ 22.4(S.V.P)
0.8 mol = x / 22.4
cross multiplication
x = 22.4 × 0.8
x = 17.92
:. the volume of 0.8 mol of nitrogen gas is 17.92dm³ or 17.92L
A bond between two atoms that SHARE electrons
