Positive or negative charge
A polyatomic ion is a cluster of covalently bonded atoms with a positive or negative charge that acts as a unit.
A polyatomic ion is a covalently bonded groups of atoms that acts as a single unit and has a positive or negative charge as a result of the formation of an ionic bond with another ion. An example of a polyatomic ion is hydroxide ion which has the chemical formula; OH− (has a charge of −1), and is made up of one oxygen atom and one hydrogen atom.
Answer:
Most compounds of Rubidium are formed by ionic bonds.
Explanation:
Answer:
Due to the presence of 4 valence electrons.
Explanation:
The tetrahedral arrangement of bonds formed by carbon and its relevance In the interaction of biomolecules occurs because the carbon atom has four electrons in their outermost shell and the four hydrogens has one electron each which result is a total of eight electrons distributed in four bonding orbitals making the structure of tetrahedral and the bond angles between these carbon atoms is approximately 109.5 degree.
The most stable conformation of 3-isopropyl-1,1dimethylcyclohexane equatorial ethyl group (more stable). The stability of ethylcyclohexane's equatorial conformer exceeds that of its axial conformer by 7.4 kJ/mol.
According to the previous section, the chair conformation with the equatorial methyl group is more stable because it reduces steric repulsion, and as a result, the equilibrium favors the more stable conformer. Strongly favoring the equatorial shape is methylcyclohexane. The methyl group is in close proximity to the axial hydrogens in the axial conformation, which has an energetically unfavorable effect known as a 1,3-diaxial interaction. The methyl group prefers the equatorial shape as a result. The conformation of ethylcyclohexane in which the ethyl group is in the equatorial position is the most stable.

Answer:
Borax bead test
Explanation:
Another test that can be used to identify colored ions in a specific compound such as salt is called "Borax bead test".
This test involves use of a clear glassy bead of borax that is joined together in a wire loop which is going to be involved in chemical reaction with the salts of certain metals.
This reaction will produce colors that we can use to identify the exact metal ions that are present.
