Cl⁻ has a greater charge density than Na⁻.
The amount of electric charge that can build up across a unit length, unit area, or unit volume of a conductor is known as charge density. In other words, it shows the amount of charge that is held in a certain field. It determines how the charge is distributed and can be either positive or negative.
We encounter electric charge density when measuring electric fields from different continuous charge distributions including linear, surface, and volume. We must also take charge density into account when analyzing current electricity. We must first comprehend this concept of density in order to comprehend charge density. The definition of density for a thing is its mass per unit volume.
Size and charge density are inversely correlated, meaning that the smaller the size, the higher the charge density. This implies that Cl has a smaller volume and a higher charge density.

Answer:
When a solid reaches the temperature of its melting point, it can become a liquid. For water, the temperature needs to be a little over zero degrees Celsius (0oC) for you to melt.
<span>Atomic number of magnesium is 12. That implies that in ground state magnesium has 2 electrons in the first level, 8 electrons in the second level, and 2 electrons in the third level. That is represented by 2 8 2. That the atom is in an excited state means that one electron (at least) is a upper level than where it is in grounded state. That situation is represented by the option (1) 2 7 3, where one electron from the second level has been promoted to the third level.</span>
Explanation:
To solve this problem, we simply use the periodic table of elements which groups elements based on their atomic numbers.
The atomic number of an element is the number of protons it contains. The protons are the positively charged particles within an atom.
- The vertical arrangement of elements on the periodic table is the group.
- The horizontal arrangement of elements is the period.
Now;
Noble gases belongs to group 18
Alkali earth metals belongs to group 2
Halogens belongs to group 17
Alkali metals belongs to group 1
Transition metals belongs to group 3-12
