Answer:
17 electron
Explanation:
because the number of the proton and number of electron is equal if ther is no charge
Inhibitor
Explanation:
Adding an inhibitor will slow down a chemical reaction. Inhibitors works like a negative catalyst.
The addition of a foreign body can influence the rate of a reaction.
- When a foreign body slows down a reaction, it is called an inhibitor.
- An inhibitor is a negative catalyst that will slow down a reaction.
- Such substances do not allow a reaction to proceed freely and very fast.
- They work in the opposite way a normal catalyst would.
- It is good to know conditions and chemicals that can inhibit a chemical reaction.

Answer: This option is incorrect: <span>B. Covalent compounds are held together by much stronger interparticle forces than are ionic compounds.
Justification:
Ionic bonds, held by ionic compounds, are much stronger than covalent bonds, held by covalent compounds.
In ionic bonds one element yields one or more electrons forming a cation (a positively charged ion) and the other element accepts the electrons forming an anion (a negatively charged ion).
The anion and the cation are electrostatically atracted by each other. This electrostatic atraction force, named ionic bond, is very strong.
As result of this, the ionic compounds form strong crystals with high boiling and fusion points. A good example of this the sodium chloride, formed by the union of cation Na(+) and anion Cl(-).
The covalent bonds are result of sharing electrons and do not form ions. This bond is weaker than the ionic bond.

Answer:
METAL: found in periodic table, lithium, shiny, lose electrons easily, good conductor, elements
NONMETAL: brittle, ductile, semimetals, found in periodic table, often gain electrons, semiconductors, carbon, shiny, poor conductor, elements
METALLOID: solid, non- ductile, malleable, found in periodic table, silicon, shiny, can be liquids, elements
