Chemistry

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.

An iconic bond is formed when one or more electrons are transferred from one atom to another. And a covalent bond forms when electrons are shared between atoms

hydrogen bonding only occurs between a very electronegative atom and a hydrogen covalently bonded to an electronegative atom.

Pyramidal like NF 3

Chemical elements are solids, liquids or gases. Compounds are also solids, liquids or gases.

In circular orbits around each nucleus.

Binary molecular compounds are formed from the reaction between two nonmetals. The formulas for binary molecular compounds are written in a similar manner with ionic compounds.

Its about 11.2 L :)

Ar

(argon)

If the question is about Ni (without space), nickel metal, it can be NiO,

but the reaction to form it is not very likely, Ni is a rather precious metal.

.430 mol

PCl5, MgS and Agl are binary compounds.

Metals. :)

Dmitri Mendeleev (in his periodic table, who arranged according to increasing atomic mass).

Niels Bohr in the modern periodic table, where the elements are arranged in increasing atomic number.

Approximally 0.275 moles.

The molar mass of Ca C O3 is ~ 40+12+3*16 = 100g/mol

27.50g = x mol *100g/mol

27.50g/(100g/mol) = x mol

0.275 g/(g/mol) = x mol

0.275 mol = x mol

The net ionic equation that describes the reaction when these solutions are mixed is the net summation. This is the net ionic equation for the chemical reaction.
