A maximum of two electrons with opposite spin can be contained in any orbital. The first shell contains two electrons and a single 1s orbital. Eight electrons—two in a 2s orbital and six in three 2p orbitals—are housed in the second shell. There are eighteen electrons in the third shell: two in a 3s orbital, six in three 3p orbitals, and ten in five 3d orbitals.

From lowest to highest, the electron orbital energy levels are as follows: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.

Helium is the only one of these substances that has a single atom, making it a monoatomic molecule. Since CO2, N2O, and H2 have bonds, none of them are monoatomic.

The azimuthal quantum number (subshell), l, can have orbital values between 0 and (n-1). sum of the ‘n’ values.

Since l=0,1,2,3 in n=4, there are four subshells, s, p, d, and f, respectively.

m is the magnetic quantum number.

I have a total of 2l+1 values, ranging from -l to +l.

A maximum of two electrons can be occupied by each orbital.

Electron count = 2×16=32

Mg+2 = 12- 2 = 10 Na+ = 11-1 = 10

Both have ten electrons as a result.

B is the right choice.

The molecule in blood that carries oxygen is called hemoglobin. The entire hemoglobin molecule, which has a molecular weight of roughly 64.500, is made up of four globin subunits and an iron-containing heme.

Hydrogen is 68,000 times lighter than hemoglobin.

Ionization energies are influenced by an atom’s atomic radius.

Principal quantum numbers (n) and azimuthal quantum numbers (l) are the two different kinds of quantum numbers. The number of shells is actually the principal quantum number, n. The number of subshells is actually the azimuthal quantum number, or l. The azimuthal quantum number (l) will equal 1 in accordance with the n-1 rule.

“2p,” where “n=2” is represented by 2 and “l=1” by p, which stands for the second subshell.
