GENERAL KNOWLEDGE

Detailed explanation-1: -Valence electrons are the electrons that are located in the outermost energy level of an atom. Some elements will have the same number of valence electrons in a neutral atom, but the number and arrangement of the electrons will be different.

Detailed explanation-2: -Electrons that are in the outermost energy level of an atom are called valence electrons. The position of an element within a period can help to determine the element’s electron configuration and number of valence electrons.

Detailed explanation-3: -The electrons surrounding an atom are located in regions around the nucleus called “energy levels”. An energy level represents the 3-dimensional space surrounding the nucleus where electrons are most likely to be.

Detailed explanation-4: -Answer and Explanation: The electrons on the outermost energy level of an atom are called valence electrons. These are the electrons involved in bonding and chemical reactions.

Detailed explanation-5: -Electrons are located at fixed distances from the nucleus, called energy levels. You can see the first three energy levels in the Figure below. The diagram also shows the maximum possible number of electrons at each energy level. Electrons at lower energy levels, which are closer to the nucleus, have less energy.
