either gained or lost an electron

Answers

Answer:

D

Explanation:

An ion is created because an atom doesn't have a balanced number of protons and electrons. A positive ion is created by an atom losing an electron and a negative ion is created by an atom gaining an electron.

The answer is D. What makes a neutral atom neutral is that it has an even number of protons and neutrons. If the number of protons and neutrons are unbalanced, it is now an ion.

What is the influence of temperature on a chemical change?

Answers

Answer:

Increasing the temperature will cause chemical changes to occur faster. Decreasing the temperature, causes the particles to lose energy which causes them to move around less and slower. The less they move, the less collisions occur, and the less reactions occur between the chemicals = slower reaction rate.
