In which compound does the first element have an ion charge of 1+? 1.)
CoCl2
2.)
ClF3
3.)
ZnO
4.)
Au2S

#4 is the correct answer

Explanation:

For #1, Cobalt has an ionic charge of +2

Chloride has a charge of -1, and Zinc has an ionic charge of +2. Therefore, Au has a charge of +1

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
