N Nitrogen
14.0
Which two parts are needed to make a neutral atom of nitrogen?
A. Electron clouds with a total of seven electrons
B. A nucleus with three protons and four neutrons
O C. A nucleus with seven protons and seven neutrons
D. Electron clouds with a total of 14 electrons

A. Electron clouds with a total of seven electrons

Explanation:

A neutral atom of nitrogen must have a total number of 7 electrons in its cloud.

This is the required number of electrons to bring nitrogen into its state of neutrality.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
