Answer:
Nonpolar covalent bonds are a type of bond that occurs when two atoms share a pair of electrons with each other. These shared electrons glue two or more atoms together to form a molecul
Explanation:
Answer:
the law of conservation states that no atoms are lost or made during a chemical reaction but they react in ways to create something different from themselves
The correct option is A.
All the elements in group 1 and hydrogen has only one electron in their outermost shells, thus, they all have similar electron configuration. The elements int the periodic table are grouped in such a way that, all elements in the same group have the same number of electrons in their outermost shells. This is one of the principal reason why hydrogen is grouped with group 1 elements.<span />
Isotopes are the same elements with the same number of portions but different numbers of neutrons
For instance, the element carbon exists as several isotopes, each having the exact same number of protons (otherwise, it would no longer be carbon if the # of protons changes), and a different number of neutrons
