A nitrogen ion has a mass of 14 and a charge of +2. Which subatomic particles does it contain? (1 point) O 2 protons, 6 neutrons, and 6 electrons
O 7 protons, 7 neutrons, and 5 electrons
O 4 protons, 4 neutrons, and 6 electrons
o 7 protons, 7 neutrons, and 9 electrons

BE CUZ IT POOPS SO BADLY IN YOUR MOUTH AND TATI MUT

Explanation:

SSS

7 protons, 7 neutrons, and 5 electrons

Explanation:

the formula for atomic weight=no.of protons + no. of electrons this shortens the options into b or d and second part says that the ion has charge +2 which means it has lost two electrons. so no. of electrons=no.of electrons in nitrogen atom - 2=5.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
