Answer:

B will give up two electrons to form bonds.

Explanation:

B has 12 electrons, it means that the electronic configuration of B is; 1s2 2s2 2p6 3s2. The implication of this is that B must be an element of group 2 since it has an outermost electron configuration of ns2.

The elements of group 2 form ionic bonds by loss of two electrons. This implies that B will form bonds by loss of two electrons.

An FM station broadcasts music at 93.5 MHz (megahertz, or 10⁶ Hz). Find the wavelength (in m, nm, and Å) of these waves.

Grace [21]

Answer:

The wavelength in m = 3.208 m

The wavelength in nm = $3.208\times 10^9 nm$

The wavelength in Å = $3.208\times 10^{10} \AA$

Explanation:

To calculate the wavelength of light, we use the equation:

$\lambda=\frac{c}{\nu}$

where,

$\lambda$ = wavelength of the radiation

c = speed of light = $3.0\times 10^8m/s$

$\nu$ = frequency of wave

We have :

Frequency of the wave = $\nu =93.5MHz=93.5\times 10^6 Hz$

$1 Hz = 1s^{-1}$

Wavelength of the wave = $\lambda$

$\lambda =\frac{c}{\nu}$

$\lambda=\frac{3\times 10^8 m/s}{93.5\times 10^6 s^{-1}}=3.208 m$

$1 m = 10^9 nm$

$3.208 m= 3.208\times 10^9 nm$

$1 m = 10^{10} \AA$

$3.2086 m= 3.208\times 10^{10} \AA$

The wavelength in m = 3.208 m

The wavelength in nm = $3.208\times 10^9 nm$

The wavelength in Å = $3.208\times 10^{10} \AA$
