slavikrds [6]

Answer:

The total number of orbitals for a given n value is n2.

Explanation:

For a hydrogen atom with n=1, the electron is in its ground state; if the electron is in the n=2 orbital, it is in an excited state.

An unknown compound has the following chemical formula:

Softa [21]

Answer:

Formula of the compound = $P_2O_5$

Explanation:

Given,

No. of mole of O = 8.20 mol

No. of mole of P = 3.30 mol

Chemical formula = $P_2O_x$

Ratio of P and O = $\frac{2}{x}$

$\frac{2}{x} =\frac{3.3}{8.20} \\x \times 3.3 = 8.20 \times 2\\x = \frac{8.20 \times 2}{3.3} \\x=4.9969\\ = 5$

formula of the compound = $P_2O_5$

babymother [125]

Answer:

Their electrons are placed in a higher number of orbitals

Explanation:

Suppose a element be Ga .

The atomic no is 31

The configuration is given by

$\\ \sf\longmapsto 1s^22s^22p^63ss^23p^63d^{10}4s^24p^1$

$\\ \sf\longmapsto [Ar]3d^{10}4s^24p^1$
