1. Understanding Valence Electrons: - Valence electrons are the electrons located in the outermost shell of an atom. They are crucial for determining how an element will react chemically. - In the second period of the periodic table, we have the elements: Lithium (Li), Beryllium (Be), Boron...
Valence electrons are normal electrons in terms of their mass and charge. What makes valence electrons special is their location in the electron cloud. They are located in the outer shell(s) of the electron cloud of an atom. Answer and Explanation: ...

Chemists use equivalent units, or equivalents, to express the reactive capacity of a chemical species, such as electrons or ions like H+. The equivalent defines how many electrons or ions may be transferred in a chemical reaction. For example, in the aci
