Answer:
If the atom has more electrons than protons, it is a negative ion or ANION. If it has more protons than electrons, it is a positive ion.
Explanation:
Positive ions are typically metals or act like metals. Many common materials contain these ions. Mercury is found in thermometers, for instance, and aluminum is a metal that is found in a surprising amount of things.

The name of the ion is chloride.
To name a <em>monatomic anion</em>
• <em>Drop the ending</em> of the element name (chlor<u>ine</u> → chlor)
• <em>Add the ending</em> <em>ide</em> (chlor + ide → chloride)
Molarity can be defined as the number of moles of solute in 1 L of solution.
M = n/V
Where M is the molarity of the solution (M or mol/L), n is the moles of the solute (mol) and V is the volume of the solution (L).
Here, solute is KF.
n = <span>0.250 mol
</span>V = 0.500 L
M = ?
By applying the formula,
M = 0.250 mol / 0.500 L
M = 0.500 mol/L
Hence, the molarity of KF solution is 0.500 mol/L.
