Reactividad

The video explains how the reactivity of elements is influenced by the number and arrangement of electrons in their atoms. Atoms strive for stability by achieving a full outer electron shell. Atoms with 1 or 2 outer electrons tend to lose them, while those missing 1 or 2 electrons tend to gain them, making them highly reactive.

What is the primary focus of chemical reactions?

• The formation of new compounds

• The reactivity of elements

• The color change in substances

• The temperature change in reactions

How does the arrangement of electrons influence an element's reactivity?

• It determines the element's color

• It changes the element's density

• It influences how easily an element can form bonds

• It affects the element's melting point

Why do atoms with nearly full outer electron shells tend to gain electrons?

• To achieve a stable electron configuration

• To increase their atomic mass

• To become more reactive

• To decrease their size

What happens to atoms with only 1 or 2 outer electrons?

• They tend to gain electrons

• They become inert

• They tend to lose electrons

• They form covalent bonds

What is the result of an atom achieving a full outer electron shell?

• It becomes unstable

• It loses its identity

• It becomes highly reactive

• It achieves stability
