Calculate the energy of the violet light emitted by a hydrogen atom with a wavelength of 410.1 nm. a. 1.23 × 10-19 J

b. 8.13 × 10-19 J

c. 4.85 × 10-19 J

d. 2.06 × 10-19 J

e.5.27 x 10-19 J

4.85 x 10⁻¹⁹J

Explanation:

Given parameters:

Wavelength = 410.1nm

Unknown:

The energy of the violet light = ?

Solution:

The energy of a wave can be derived using the expression below;

    E =

h is the planck's constant

c is the speed of light

  Insert the parameters and solve;

      E =   = 4.85 x 10⁻¹⁹J

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
