Two neutral atoms, one being a nonmetal and the other a metal, form an ionic bond when the nonmetal uses energy to remove valence electrons from the metal.
Since a metal is not very electronegative but a nonmetal is, the nonmetal can remove the metal’s valence electrons.
In a perfect scenario, both atoms, now ions, will have octets. An octet is formed when an ion has a full valence shell (usually noted with 8 valence electrons).
Explanation:
The given chemical reaction will be as follows.
Also, mass deposited can be calculated using the formula as follows.
W = Zit
where, W = weight or mass of the substance
Z = electrochemical equivalent
i = current
t = time in seconds
Calculate value of Z for the given reaction as follows.
Z =
molar mass of Al = 26.98 g/mol
Z =
= g/mol
Therefore, putting the given values into the above formula as follows.
W = Zit
=
= 0.328 g
Thus, we ca conclude that 0.328 g of aluminium can be electroplated in the given situation.

Answer:
B. 39.1 g.
Explanation:
- It is known that every 1.0 mole of any atom contain Avogadros no. of atoms (6.022 x 10²³).
<em>∴ 6.02 x 10²³ atoms are in 1.0 mol of K.</em>
- We need to calculate the mass of 1.0 mol of K using the relation:
<em>∴ </em>mass of K = no. of moles of K x atomic mass of K = (1.0 mol)(39.1 g/mol) = 39.1 g.
