Why are only certain colors absorbed by and emitted from an atom?

1 answer:

6 0

The way I would explain it is quite difficult to understand, so this is what Google says. "The wavelength (or equivalently, frequency) of the photon is determined by the difference in energy between the two states. These emitted photons form the element's spectrum. The fact that only certain colors appear in an element's atomic emission spectrum means that only certain frequencies of light are emitted." I hope this helped.

Which types of atomic orbitals of the central atom mix to form hybrid orbitals in:<br> (c) PF₅;

zloy xaker [14]

The atomic orbitals of the central atom mix to form hybrid orbitals are one s and three p.

<h3>Which atomic orbitals are used to form hybrid orbitals?</h3>

Pauling supposed that in the presence of four hydrogen atoms, the s and p orbitals form four equivalent combinations which he called hybrid orbitals.

<h3>How many bonds does PF5?</h3>

Phosphorus pentafluoride has 5 regions of electron density around the central phosphorus atom (5 bonds, no lone pairs).

The resulting shape is a trigonal bipyramidal in which three fluorine atoms occupy equatorial and two occupy axial positions.

Is the solubility of FeFe (OH)(OH) 33 increased, decreased, or unchanged on addition of each of the following substances? Write

Shalnov [3]

Answer:

a) solubility increases

b) solubility decreases

c) solubility increases

Explanation:

I) Fe^3+(aq) + 3Br^- --------> FeBr3 (aq) solubility increases

II) Fe^3+(aq) + 3OH^- ---------> Fe(OH)3(s) solubility decreases

III) Fe^3+(aq) + 6CN^- -----------> [Fe(CN)6]^3- (aq) solubility increases

The ionic equations shown above shows the possible changes in solubility when Fe(OH)3 is added to each of the solutions mentioned in the question.
