Answer:

8)

Potential Explosions

Radiation

Radioactive Waste

9)

1st option

10)

Nuclear Fission is not a good source of energy. This is by reason of only 0.7% of the uranium being captured. This is small even if one doesn't mention that only 40% of that 0.7% is converted into usable energy. There are also chances that the power plant could explode during conversion. All of this evidence points to the fact that Nuclear Fission and Nuclear Energy themselves should not be relied on.

the element nitrogen has an atomic number of 7 and an atomic mass of 14 how many protons, neutrons and electrons are in a atom o
Nat2105 [25]

Answer: By definition, if  the atomic number  = 7 , then there are 7 protons, 7 electrons, and 8 neutrons!

Explanation:

The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles. Why? Because matter is electrically neutral, and positive and negative particles must be equal.

Electrons have negligible mass; the mass number depends on the number of protons contained within the nucleus, PLUS the number of neutrons. Given that we have  15  N , there must be 8 neutrons contained within the nucleus.  does this help?
