What is its main function in the atmosphere for nitrogen

Answers

Answer 1
Answer: Nitrogen is very cold. If touched, it could freeze a person instantly. It is used in our atmosphere as a way for us to not be harmed by the harmful rays of the sun. The coldness helps prevent us from getting the full intense heat of the sun that will kill us.

When people use the term "observable universe" it means that the light from other parts of the universe hasn't yet had time to reach us, so we cannot see it.

When a potassium atom forms an ion, it loses one electron. What is the electrical charge of the potassium ion?A. -1
B. -2
C. +2
D. +1

Answers

If a potassium atom loses one electron than it becomes a +1 charge, because the electrons are negative and the nucleus is positive (the positive comes from the protons). The protons and electrons balance out so it has a neutral charge, but if the atom loses an electrons it has a positive charge, but if the atom gains an electron than it becomes negative. the charge (+/- and the number) of the atom depends on how many electron the atom gains/loses. 
the answer is (D.) +1

I hope this helps.

When a potassium atom loses one electron, it forms a potassium ion. Since electrons carry a negative charge, losing one electron results in an overall positive charge for the ion. Therefore the correct answer is (D).

A potassium atom normally has 19 protons and 19 electrons. The number of protons and electrons is equal, so the atom is electrically neutral overall.

However, when a potassium atom loses one electron, it means that it now has 19 protons and only 18 electrons. Since protons are positively charged and electrons are negatively charged, losing one negatively charged electron leaves the atom with a net positive charge.

Since there is one more positive charge than a negative charge, the potassium ion has a positive charge of +1. This means the potassium ion has one more positive charge than it has negative charges, making it a cation with a +1 electrical charge.

In summary, when a potassium atom loses one electron, it becomes a potassium ion with a positive charge of +1. Therefore the correct answer is (D).
