Question

the element carbon (c) is most likely to form covalent bonds with the element beryllium (be). krypton (kr). selenium (se). sodium (na).

Explanation:

Covalent bonds form between non - metals. Carbon (C) is a non - metal. Beryllium (Be) is a metal, sodium (Na) is a metal. Krypton (Kr) is a noble gas and is generally unreactive. Selenium (Se) is a non - metal. So carbon is most likely to form covalent bonds with selenium.

Answer:

selenium (Se).
