Answer:

See explanation

Explanation:

In each chlorine atom, there are seven valence electrons. Recall that each chlorine atom only needs one electron in order to achieve the stable octet structure.

As a result of this, the chlorine atoms in Cl2 share two electrons contributed by each of the bonding atoms. By so doing, each atom achieves the stable octet as required by the octet rule.

What is the net ion charge of Beryllium?

KATRIN_1 [288]

Explanation:

Beryllium is a group 2 element and its atomic number is 4. Electronic configuration of beryllium is $1s^{2}2s^{2}$ .

Since, a beryllium contains two valence electrons so, in order to attain stability it will readily lose its 2 valence electrons.

Therefore, a beryllium atom upon losing two valence electrons will acquire a +2 charge.

Thus, we can conclude that the net ion charge of Beryllium is +2.

Microwave ovens emit microwave energy with a wavelength of .129 m. What is the energy of exactly one photon of this microwave ra

gayaneshka [121]

λ=Wavelength = .129 m = 0.129 m

E = energy = ?

h =Planck constant = 6.63 × 10^-34 J.s

f = frequency of photo/ electromagnetic radiation = c/λ

c = Speed of light in a vacuum = 3 × 10^8 m/s

___o___o___

$E = hf \\ \\ E = h \frac{c}{λ} \\ \\ E = 6.63 \times {10}^{ - 34} \frac{3 \times {10}^{8} }{0.129} \\ \\ E = \frac{6.63 \times {10}^{ - 34} \times 3 \times {10}^{8} }{0.129} \\ \\ E = \frac{663 \times {10}^{ - 36} \times 3 \times {10}^{8} }{129 \times {10}^{ - 3} } \\ \\E = \frac{1989 \times {10}^{ - 28} }{129 \times {10}^{ - 3} } \\ \\ E = 15.4 \times {10}^{ - 25} J \\ \\ E = 1.54 \times {10}^{ - 24} J$
