a covalent bond should be present between substances when the difference in their electronegativities is less than around 1.7. however this is a rough guide, as there is no real distinction between covalent and ionic bonds, there are really just increasingly polar covalent bonds. or for a more gcse-level answer, you can expect that covalent bonds should be formed when non-metals react with other non-metals.

What is the covalent compound of2?
The compound of O2 is dioxygen. It is a diatomic molecule made up of two oxygen atoms bonded together by a covalent bond.
Do the relative positions of sucrose in the periodic table agree with the theoretical prediction about the kind of compound these elements should form?
Yes, the relative positions of carbon, hydrogen, and oxygen in the periodic table agree with the theoretical prediction about the kind of compound they should form. Carbon and oxygen are in the same group and tend to form covalent compounds, while hydrogen typically forms compounds with other elements through ionic or covalent bonds. Sucrose, a compound made of carbon, hydrogen, and oxygen, is a covalent compound in line with these predictions.
True or false the first element in a compound should have no charge?
False, all compounds are electrically neutral.
What is the name of the covalent compound BH3?
Mass?Here it is with an example.. a compound of 78.14% Boron and 21.86% hydrogen with an experimental mass of 27 to 28 g. The empirical formula is as above BH3and Molecular formula is B2H6Molar mass / by empirical formula mass should give you an integer to multiply the empirical formula (BH3) with. This time it was 2 (rounded).
How do you distinguish between an ionic and a covalent compound?
Ionic compounds are formed between a metal and a nonmetal, where electrons are transferred from one atom to another. Covalent compounds are formed between nonmetals, where electrons are shared between atoms. Ionic compounds generally have higher melting and boiling points due to their strong electrostatic forces, while covalent compounds have lower melting and boiling points due to weaker intermolecular forces.
When should you expect a compound to contain an ionic bond?
When all reactants are non-metals
Is cyclohexane an aromatic compound?
No, cyclohexane is a cycloalkane and not an aromatic compound. Aromatic compounds have a specific type of stability due to resonance in their pi electron system, while cyclohexane does not possess this type of stability.
What is the covalent compound?
The systematic name of this compound is Oxygen(II) Fluoride. N.B. This compound is a fluoride of oxygen. It should not be mistaken as a oxide of fluorine.
What is the covalent compound of2?
The compound of O2 is dioxygen. It is a diatomic molecule made up of two oxygen atoms bonded together by a covalent bond.
H2O an organic compound?
Organic compounds should contain Carbon.So it is not organic.

True or false the first element in a compound should have no charge?
False, all compounds are electrically neutral.
C2H4 is it molecular or ionic?
No, this molecule is not ionic. It is composed of all non metal atoms. In order to be ionic, the compound should consist of the following combinations: metal + nonmetal, or metal + polyatomic ion, or 2 polyatomic ions together.
Does a compound always contain the same element in the same proportions?
Yes, except that "element" should be pluralized; a compound always has at least two elements.
What element can contain hydrochloric acid?
Assuming you mean "contain" in a physical sense (because chemically speaking, no element can "contain" a compound) ... Sulfur should work. Carbon ought to work as well.
