Question

1. calculate the number of valence electrons in methylene chloride, ch₂cl₂. valence electrons

Explanation:

Step1: Determine valence electrons of each atom

Carbon (C) has 4 valence electrons, hydrogen (H) has 1 valence electron, and chlorine (Cl) has 7 valence electrons.

Step2: Calculate total valence electrons

For \(CH_2Cl_2\), there is 1 C atom, 2 H atoms, and 2 Cl atoms.
The total valence electrons \(=4+(1\times2)+(7\times2)\)
\(=4 + 2+14\)
\(=20\)

Answer:

20
