Answer:
1.5217391304348 gram/cubic centimeter is the density
3.5 gram/2.3 cubic centimeter
non-metals are brittle.
but for brittle property, they need to be solid.
sulphur is solid at STP.
Argon(Ar) is a gas at STP, so it cannot be brittle.
The correct answer for the question that is being presented above is this one: "Electrovalency is characterized with the transferring of one or more electrons from one atom to another together with the formation of ions and as well as the number of positive and negative charges.
The Lewis and Langmuir theory of electrovalency (and as well as Kossel's) is dealing with Ionic bonds.
Lewis: electron-pair sharing, octet rule, Lewis Symbols or StructureLangmuir: introduced term "covalent" bond, and popularized Lewis's ideas
The Lewis-Langmuir electron-pair or covalent bond is referred as the homopolar bond, where the complete transfer of electrons give rise to ionic, or electrovalent bond (1) through attraction of opposite charges.
