WebOct 27, 2024 · The metalloid boron exhibits many similarities to its neighbor carbon and its diagonal neighbor silicon. All three elements form covalent compounds. However, boron has one distinct difference in that its 2s 2 2p 1 outer electron structure gives it one less valence electron than it has valence orbitals. Although boron exhibits an oxidation state ... WebHydrogen. 8. Identify a nonmetal with one valence electron. Carbon. 9. Identify the element with four valence electrons and the least mass.
