How many covalent bonds does helium form
WebHelium has two electrons; therefore, it can completely fill the lowest shell with its two electrons. If you look at the periodic table, you will see that hydrogen and helium are the only two elements in the first row. This is because they only have electrons in their first shell. WebYou can also classify bonds by look-ing at the characteristics of the substance. polar covalent bond. nonpolar covalent bond Topic Link Topic Link Refer to the “Periodic Table” chapter for more about electronegativity. nonpolar covalent bond a covalent bond in which the bonding electrons are equally attracted to both bonded atoms polar ...
