Unabbreviated electron configuration of magnesium
fenix001 [56]

Answer:

Mg₁₂ = 1s² 2s² 2p⁶ 3s²

Explanation:

Abbreviated and unabbreviated electronic configuration:

The abbreviated electronic configuration uses the noble gas configuration i.e complete electronic shells. For example, the atomic number of neon is ten and magnesium is twelve. The abbreviated electronic configuration of magnesium is written by using the neon abbreviation in following way:

The electronic configuration of neon is given below:

Ne₁₀ = 1s² 2s² 2p⁶

The abbreviated electronic configuration of magnesium:

Mg₁₂ = [Ne] 3s²

While the unabbreviated electronic configuration is written without using noble gas electronic configuration.

Unabbreviated electronic configuration of magnesium:

Mg₁₂ = 1s² 2s² 2p⁶ 3s²

How many nitrogen atoms are in 2.79 mo.of NH3
alexandr1967 [171]
1 mol of any particles has 6.02 * 10 ²³ particles.

If we look at 1 NH3 (1 mol NH3 or 1 molecule NH3), we can see that 1 molecule NH3 has 1 atom of N and 3 atoms of H; also 1 mole of NH3 has 1 mole of N atoms and 3 moles of H atoms.

So, 1 mol of NH3 has 1 mol of N atoms,
 and 2.79 mol NH3 have 2.79 mol of N atoms.

2.79 mol of N atoms* 6.02 * 10 ²³ N atoms/ 1 mol N atoms = 1.68*10²⁴ N-atoms 

 Answer is 1.68*10²⁴ N-atoms.
