Atoms tend to gain, share, lose valence electrons until each atom has the same number of valence electrons as the ____________.

my answer: nucleus

No, the correct answer is: atoms tend to gain, share, or lose valence electrons until each atom has the same number of valence electrons as the noble gas in their respective periodic group.

Your answer is incorrect. The correct completion for the given statement is "as the nearest noble gas."

Atoms tend to gain, share, or lose valence electrons to achieve a stable electron configuration similar to that of a noble gas. Noble gases are the elements in Group 18 of the periodic table, including helium, neon, argon, krypton, xenon, and radon. These gases have full valence electron shells and are considered stable because they do not readily form chemical bonds with other elements.

To determine the number of valence electrons an atom should have to attain a noble gas configuration, you can refer to the periodic table. Valence electrons are found in the outermost energy level, also known as the highest principal energy level. The group number in which an element is found on the periodic table usually corresponds to the number of valence electrons it possesses.

For example, elements in Group 1, such as hydrogen and lithium, have one valence electron. Elements in Group 2, such as beryllium and magnesium, have two valence electrons, and so on.

By gaining, sharing, or losing valence electrons, atoms can achieve a stable electron configuration and become more chemically stable, similar to the noble gas they are striving to emulate.

yes, outer shell full

not as the nucleus, but as the noble gas

atoms tend to gain, share, and lose electrons in order to be stable.

The most stable elements are the noble gas
