<span>The outer planets—Jupiter, Saturn, Uranus, and Neptune—are made up of mainly </span>hydrogen, helium and nitrogen.
Jupiter and Saturn are primarily made up of hydrogen and helium. However, while Uranus and Neptune are primarily composed of hydrogen and helium also, they consist of more ices and methane than Jupiter and Saturn.
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.
It means it’s neutrally charged! Protons are positive while electrons are negative, so they balance each other out. Neutrons are neutral so they don’t weigh in.
