how many valence electrons are in the methyl ammonium ion ch₃nh₃⁺?

Explanation:

Step1: Determine valence electrons of each atom

Carbon (C) has 4 valence electrons, hydrogen (H) has 1 valence electron, nitrogen (N) has 5 valence electrons.

Step2: Calculate total valence - electrons before charge consideration

There is 1 C atom, 6 H atoms, and 1 N atom. So the total before considering the charge is (4+(1\times6)+5 = 15) electrons.

Step3: Account for the positive charge

The (CH_3NH_3^+) ion has a +1 charge, which means it has lost 1 electron. So the number of valence electrons is (15 - 1=14).

Answer:

14
