Use the periodic table to determine the number of valence electrons in the element Calcium (Ca). How many electrons will calcium gain or lose when it forms an ionic bond? Explain.

Calcium would lose 2 electrons when forming an ionic bond, so it’s new electron configuration would be 2-8-8. it loses 2 because it’s closer to having a full valence shell by losing the 2

how fossil fuels are formed?? answer pls asap

Answers

After the remains of living organisms (plants and animals) were buried under the layers of the earth's crust, they were exposed to very high temperatures and pressures, which led to the concentration of carbon in it and thus turning it into fossil fuels used to produce fossil energy.

The composition of fossil fuels depends on the carbon cycle in nature, and is extracted from fossil materials such as coal, black petroleum coal, natural gas, and petroleum.

How does gravity change your weight?

Answers

That is, the weight of an object is determined by the pull of gravity on it. Thus, an object's physical weight may change from place to place

As your body grows, you will have more mass, which also means you will weigh more. That's because when you're on the earth, the amount of gravity that pulls on you stays the same. So when your mass changes, so does your weight!
