How does the number of valence electrons in an element influence its chemical properties?
A
It determines the element's atomic mass.
B
It determines the element's reactivity and the types of bonds it can form.
C
It has no impact on the element's chemical properties.
D
It only affects the element's physical state at room temperature.
Verified step by step guidance1
Understand that valence electrons are the electrons in the outermost shell of an atom and are primarily responsible for chemical behavior.
Recognize that the number of valence electrons determines how an element interacts with other atoms, influencing its ability to gain, lose, or share electrons.
Know that elements with similar numbers of valence electrons tend to exhibit similar chemical properties and reactivity patterns.
Realize that the types of chemical bonds an element can form (ionic, covalent, metallic) depend on its valence electron configuration.
Conclude that the number of valence electrons directly affects an element's reactivity and bonding, rather than its atomic mass or physical state.
