PO_4^{-3} and NH^{4+} are polyatomic anions composed of two or more atoms.

<h3>What is a polyatomic anion?</h3>

A polyatomic ion is an ion composed of two or more atoms. Examples: The hydroxide cation (OH^-) and the phosphate cation (PO_4^{3-}) are both polyatomic ions.

PO_4^{-3} and NH^{4+} are the polyatomic anions because both contain more than 1 atom.

Hence,PO_4{-3} and NH^{4+} are polyatomic anions composed of two or more atoms.

It is a white, solid ionic substance made up of the cations sodium (Na+) and the anions hydroxide (OH). Sodium hydroxide is a chemical that manufacturers utilize to make things like soap, rayon, paper, explosives, colors, and petroleum products. Processing cotton fabrics, metal cleaning and processing, oxide coating, electroplating, and electrolytic extraction are further uses for sodium hydroxide.

Can any of you guys help me with this. Can y’all give me some facts about nucleus protons netrons and electrons :)
Mumz [18]

Answer:

the nucleus is the center of the atom, made up of protons and neutrons, without the nucleus you'd just have a bunch of electrons floating around; the nucleus is positively charged

protons are the positively charged particles that sit within the nucleus

neutrons are particles of no charge that sit within the nucleus, and because they have no charge, they do not cancel out the positive charge of the protons, making the nucleus positive

electrons are negatively charged particles that float around the nucleus in an area known as the electron cloud, they orbit around the nucleus because they are attracted to the positive charge of the nucleus (caused by the protons), with charges, opposites attract
