How many valence electrons are in the methyl ammonium ion CH3NH3+
12
To determine the number of valence electrons in the methyl ammonium ion (CH3NH3+), please follow these steps:
Step 1: Identify the valence electrons of each element
- Carbon (C) has 4 valence electrons
- Hydrogen (H) has 1 valence electron
- Nitrogen (N) has 5 valence electrons
Step 2: Determine the number of each element in the molecule
- The formula CH3NH3+ indicates one carbon atom, three hydrogen atoms, and one nitrogen atom.
Step 3: Calculate the total number of valence electrons
- Carbon: 1 atom × 4 valence electrons = 4 valence electrons
- Hydrogen: 3 atoms × 1 valence electron = 3 valence electrons
- Nitrogen: 1 atom × 5 valence electrons = 5 valence electrons
Adding these together: 4 + 3 + 5 = 12 valence electrons.
Therefore, there are 12 valence electrons in the methyl ammonium ion (CH3NH3+).
To determine the number of valence electrons in the methyl ammonium ion (CH3NH3+), we first need to identify the valence electrons contributed by each atom in the ion.
The methyl ammonium ion (CH3NH3+) consists of a methyl group (CH3) and an ammonium group (NH3+).
The methyl group (CH3) contains one carbon atom (C) and three hydrogen atoms (H). Each carbon atom contributes four valence electrons, and each hydrogen atom contributes one valence electron. So, the methyl group contributes 4 valence electrons from carbon and 3 valence electrons from hydrogen, for a total of 4 + 3*1 = 7 valence electrons.
The ammonium group (NH3+) contains one nitrogen atom (N) and three hydrogen atoms (H). The nitrogen atom contributes five valence electrons, and each hydrogen atom contributes one valence electron. However, since the ammonium ion (NH3+) has a positive charge (+), it means that one of the valence electrons on nitrogen has been lost. Therefore, nitrogen contributes only four valence electrons instead of five. So, the ammonium group contributes 4 valence electrons from nitrogen and 3 valence electrons from hydrogen, for a total of 4 + 3*1 = 7 valence electrons.
Summing up the valence electrons contributed by the methyl group and the ammonium group, we get 7 + 7 = 14 valence electrons in the methyl ammonium ion (CH3NH3+).
