The ions F⁻, Na⁺, Mg²⁺, and Al³⁺ have 10 electrons, as Ne, the closest noble gas.
To determine the number of electrons of an ion, we need to consider:
- The atomic number (Z): It establishes the number of protons and electrons in the neutral species.
- The charge: It indicates the number of electrons gained (negative charge) or lost (positive charge).
F has 9 electrons (Z = 9) and it gains 1 electron to form F⁻. The total number of electrons is 9 + 1 = 10.
Na has 11 electrons (Z = 11) and it loses 1 electron to form Na⁺. The total number of electrons is 11 - 1 = 10.
Mg has 12 electrons (Z = 12) and it loses 2 electrons to form Mg²⁺. The total number of electrons is 12 - 2 = 10.
Al has 13 electrons (Z = 13) and it loses 3 electrons to form Al³⁺. The total number of electrons is 13 - 3 = 10.
The ions F⁻, Na⁺, Mg²⁺, and Al³⁺ have 10 electrons, as Ne, the closest noble gas.

<h3><u>Answer and explanation;</u></h3>
Ideal gas law is the mathematical relationship among pressure, volume, temperature, and the number of moles of a gas.
The ideal gas law is given by;
PV=nRT, where
P is the Pressure
V is the volume of the gas.
n is the number of moles
R is the gas constant and
T is the temperature
I think it would be d bc water is everywhere
It is basic because of the fact that it has a strong base which is KOH and a weak acid HCN and the strong base causes it to remain more basic.
Answer = 23.2146762081 pounds.

13% of 81 = 10.53
10.53 converted to pounds (lbs) = 23.21......pounds
