The gas H2X forms discrete covalent molecules. X also forms a covalent compound with fluorine. What would you expect the molecular formula of the fluoride of X to be?

The attachment of two hydrogens with X indicates that the valency of X is 2 ,so the formula for fluoride of X may be XF2.

What is the melting point for covalent?
Covalent bonds do not melt. Compounds with covalent bonds melt and the melting point depends primarily on whether there are discrete molecules held together by intermolecular forces (which have lower melting points) or giant covalent networks such as in silica or diamond (which tend to have higher melting points).
What is the difference between ionic covalent and molecular compound?
Ionic compounds are between metals and non-metals. Molecular (covalent) compounds are between only non-metals. (Metallic compounds are between metals and other metals.) An ionic compound is a pure substance that is formed from a metal and a nonmetal. It has a fairly high melting point and is a conductor of electricity when in a molten or aqueous state. A molecular compound, on the other hand, is a pure substance that is formed from nonmetals. It has a fairly low melting point, and cannot conduct electricity regardless of state. Another important difference between the two is that an ionic compound is a crystalline solid at standard temperature and pressure (STP), whereas a molecular compound can be in a solid, gas or liquid state at STP. Molecular compound is derived from combinations of different molecules while ionic compound is derived from inducing electrical current into molecules. if the compound contains a metal bonded to a nonmetal, it is most likely an ionic compound. It the compound contains two nonmetals, it is a molecular compound.
Why do molecular compounds have low melting points and low boiling points relative to ionic substances?
The melting points and boiling points of molecular covalent compounds (ones with discrete molecules) are lower than ionic solids and giant molecule covalent compounds like (silica, SiO2) because the forces that attract them together in the solid and the liquid states (van der waals, hydrogen bonding and dispersion forces) are weaker than ionic (or covalent) bonds.
How do ionic bonds and ionic compounds differ from covenant bonds and molecules?
Ionic bonds is the attracting between opposing forces (positive and negative) while covalent bonds are atoms sharing electrons to get an inert gas configuration (8 electrons in valence shell). Covalent bonds exist as discrete molecules while ionic compounds do not exist as discrete molecules and form large crystal lattices.
Organic compounds exist as discrete molecules with much weaker intermolecular forces than those seen in ionic compounds?

what are the types of covalent bonding that we have?
Discrete covalent molecules. eg CO2, N2,CH4. Covalent networks. eg SIO2

What are the differences between molecular bonds and ionic bonds?
Molecular substances have a lower melting and boiling point than Ionic. Also, molecular substances can be two non metals joined together where as Ionic it is a metal and nonmetal. Molecular substances have covalent bonds and Ionic have Ionic bonds.

Why are the melting point and boiling point of a covaleny substance low?
The melting points and boiling points of molecular covalent compounds (ones with discrete molecules) are lower than ionic solids and giant molecule covalent compounds like (silica, SiO2) because the forces that attract them together in the solid and the liquid states (van der waals, hydrogen bonding and dispersion forces) are weaker than ionic or covalent bonds.
Would ionic or covalent molecules use the molecular formula Why?
Covalently bonded compounds are characterized by a molecular formula, because such compounds exist in the form of discrete molecules, all of the atoms of which move together as kinetic-molecular units. Ionically bonded compounds do not have molecules in this sense: Their compounds are made up of at least two kinds of ions, one positive and the other negative, and the ions in these compounds can move separately as kinetic-molecular units: If a positive ion is separated from the particular negative ion with which it was most closely associated initially in a fluid mixture, usually a solution in an ionizing solvent, of both kinds of ions, another negative ion with the same properties is always close by.
