Question

using the
as\ idea, how many bonds are made in the compound sicl4?
n = 40, a = 32, s = 8

Explanation:

Step1: Recall the formula for number of bonds

The formula for the number of bonds using the NAS idea is $\frac{N - A}{2}$, where $N$ is the total number of valence electrons if all atoms had noble - gas configurations, $A$ is the actual number of valence electrons in the atoms, and the division by 2 accounts for the fact that each bond has 2 electrons.

Step2: Substitute the given values into the formula

We are given $N = 40$ and $A=32$. Substitute these values into the formula: $\frac{40 - 32}{2}$.
First, calculate the numerator: $40−32 = 8$. Then, divide by 2: $\frac{8}{2}=4$.

Answer:

4
