It is true that human impact on one system leads to changes in more of Earth’s systems.
Answer: Option A
<u>Explanation:</u>
Human impact had created large impacts on Earth’s systems. The pollution in air, deforestation, dumping of lakes lead to several changes in environment. Also emission of carbon, methane and other hazardous gases from several manufacturing unit effect the environment.
Along with this, increase in usage of non-renewable fuels and release of CFC's emitted from AC’s, fridge lead to elimination of ozone layer making the environment open to direct UV radiation. So yes, it is true that human impact on one system leads to changes in more of Earth’s systems.
Nitrogen has 7 protons, 7 neutrons, and 7 electrons.
Seven protons, seven neutrons, and seven electrons make up nitrogen-14.
Utilize the atomic number and mass number of an atom to determine the number of subatomic particles it contains: Atomic number Equals proton count. Electron count equals atomic number. Atomic number - mass number equals the number of neutrons.
Seven protons, seven neutrons, and seven electrons make up the atom of nitrogen. The nucleus is the collection of protons and neutrons that make up the center of an atom. The 7 electrons, which are much smaller than the nucleus, orbit it in what is known as orbits. Since nitrogen-14 is a neutral atom, the number of protons in its nucleus must match the number of electrons around it.

Explanation:
This is the electron configuration of neptunium:
<span>Rn 5f4 6d1 7s2
</span>or, if you want to complicate:
<span>1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f4 6d1
</span>Since there are 93 electrons, they make up 5f4 altogether.
