If it is just one element, the Lewis diagram with two unpaired electrons will form a covalent compound with oxygen.
A compound. It can be an ionic compound or a covalent/molecular compound, depending on what elements are being combined. If one element is a metal and the other is a nonmetal, then the compound is most likely ionic. If both elements are non_metals, then the compound will be covalent, or molecular.
As a general rule, the further apart elements are on the periodic table, the more likely the compound that they form is ionic. Consequentlly, the closer they are, the more likely they will be covalent. If you have the electronegativity values for the elements in question, you can calculate whether the compound is covalent, polar covalent, or ionic. Find the absolute valule of the difference between the electronegativities of the elements. If the difference is: 0 to .5 = covalent .5 to 1.9 = polar covalent 1.9 to infinity = ionic
Covalent bonds are formed between a metal and a non-metal. Co is cobalt, a metal, so it will react with O to form CuO, a compound with ionic bonds.

These are covalent compounds formed by sharing electrons.

Molecule. A nonmetal to nonmetal covalent bond. Electronegativity is not variant enough among the nonmetals to form ionic bonds.

Covalent bonds usually form between two nonmetals/
four hydrogen atoms and one carbon atom to form methane (CH4)
Elements with intermediate electronegativities, such as carbon and hydrogen.
sulfur and oxygen.
The elements to the very left of the table are likely to bond to the elements to the very right of the table. It all depends on the amount of electrons are in the outer shell of the element. A compound of two elements favor filling the outer shell with a total of 8 electrons.
