Write an equation that shows the formation of the phosphide ion from a neutral phosphorus atom.

Explanation: Phosphorous atom is the element with atomic number 15 and thus contains 15 electrons.

Thus it is short of 3 electrons to attain stable noble gas configuration. Thus it gains three electrons and converts to phosphide ion with 18 electrons.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
