Guys pleas help: - Which element is a member of the alkaline earth metals and has 12 neutrons?
- A burnt piece of toast is covered in this element. It is the fourth most abundant element and makes up many living things.
- Which element is an inert gas found in group VIII that produces a red glow in lights?

Carbon- A burnt piece of toast is covered in this element. It is the fourth most abundant element and makes up many living things.

Magnesium- Which element is a member of the alkaline earth metals and has 12 neutrons?

Neon- Which element is an inert gas found in group VIII that produces a red glow in lights?

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
