When a covalent bond forms between two atoms how many atoms have a full outer shell of electrons?
A. one
B. two
C. zero
D. It depends on what the atoms are.
HELP PLEASEE
It's D. Usually it's up to 8
It says when two atoms bond so it would be two B. Two
When a covalent bond forms between two atoms, the goal is to achieve stability by filling the outermost electron shells of both atoms. Each atom wants to have a full outer shell, typically with eight electrons, known as the octet rule. However, there are exceptions for smaller atoms like hydrogen and helium, which follow the duet rule instead (they only require two electrons to have a full outer shell).
In a covalent bond, atoms share electrons to fulfill their electron configuration. Each atom contributes one or more electrons to the bond, resulting in a shared pair of electrons.
To determine how many atoms have a full outer shell, consider the number of shared and lone pairs of electrons. Each shared pair of electrons contributes to the electron count of both atoms involved in the bond, while lone pairs only contribute to the electron count of their corresponding atom.
In the case of a covalent bond between two atoms, if both atoms contribute electrons to the bond, then both atoms can have a full outer shell. This means that the correct answer to your question is:
B. two
However, it is worth noting that the number of atoms with a full outer shell can depend on the specific type of atoms involved in the covalent bond. Different atoms have different valence electron configurations, so the answer might vary depending on the elements in question.
