Enter the electron configuration for phosphorus. Express your answer in order of increasing orbital energy as a string without b
statuscvo [17]

Answer:

₁₅P = 1s² 2s² 2p⁶ 3s² 3p³

Explanation:

Phosphorus is the second element of group (v) with atomic number 15 and the electrons per shell are arrange as thus; 2, 8, 5.

The electronic configuration of phosphorus is

₁₅P = 1s² 2s² 2p⁶ 3s² 3p³

Or

₁₅P [Ne] 3s² 3p³

In its first shell I.e 1s shell, it has 2 electrons filling it to s-orbital requirement. In its second shell, electrons fill it in 2s² 2p⁶ filling the second orbital and attaining an octet configuration. The third shell contains 5 electrons filling 3s² 3p³ orbital.

Komok [63]

Answer:

Option (D)

Explanation:

Oil (crude and petroleum) is one of the major resources on earth in which the economy of a country is largely dependent on. These are non-renewable resources, which take thousands to million years of years in order to form.

It is highly essential. Every day, a large quantity of oil is being consumed. According to the researches done in the year 2015, it has been observed that the average global consumption of oil was 95 million barrels each day.

It has a high demand, and so it is being regularly used, and it has also been predicted that the present global oil reserves would be highly exhausted within the next 50 years.

Thus, the correct answer is option (D).
