All compounds are made out of atoms of the same element or differed elements.
KCl is an ionic compound. The electronegativity of potassium (K) is approximately 0.82. The electronegativity of chlorine (Cl) is approximately 3.16. The difference between these electronegativities is 2.34. This high electronegativity difference is what makes potassium chloride an ionic compound. If the electronegativity difference of two elements is greater than 1.7, it is considered to be an ionic compound. If the difference is between 0.4 and 1.7, the compound is considered to be polar covalent. If the difference is less than 0.4, the compound is considered to be covalent. If the difference is 0 (i.e. the two elements are the same), then the compound is considered to be pure covalent. KCl is ionic because K's electronegativity is 0.82 and Cl's is 3.16. A compound is ionic when the electronegativity on the Pauling Scale is more than 2.1. The difference 2.34, so it is ionic.
I had this same question; because dinitrogen tetroxide has 2 Nitrogen & oxygen atoms, I wrote that it is covalent. My reasoning was that it doesn't combine negative and positive charges, both nitrogen and oxygen have negative charges.
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.
It is an IONIC compound as it involves 2 non-metals.
"I believe it is Ionic." Whoever said this is wrong, it's covalent (they share an electron from each atom to stabillise themselves) with an instantaneous dipole induced dipole intermolecular force.
Hydrogen gas (H2) is a covalent compound. Any 2 of the same atoms bonded with each other is covalent.

the properties of a compound are not the same as the elements that form them.
No.

covalent because same electronegativity.

What you write for an ionic compound is called the formula unit, but the formula unit is almost always the same as the empirical formula. The answer to your question could not be the molecular formula because an ionic compound is not a molecule.
Chlorine, Cl2 is covalent. Any molecules which consist of two atoms of the same element must be covalent. In compounds with other elements chlorine can form ionic or covalent compounds.
Covalent. I had this same question and then found the answer! Hope this helps!
