All are true except the statement that ions are formed by changing the number protons in an atom’s nucleus.

A neutral atom contains the same number of protons (positive charge) and electrons (negative charge).

If there are more electrons than protons, the atom becomes a negative ion.

If there are fewer electrons than protons, the atom becomes a positive ion.

The protons are in the nucleus, where we can’t easily get at them. The electrons are outside the nucleus, so other chemicals can easily get at them and either remove them or add to their number.

Metals have only a few valence electrons, so it is fairly easy to remove them and form positive ions.

False. That reason is because the theoretical field is often in a good state, which is atleast 90% and above.

What does the empirical formula of a compound describe?

AveGali [126]

It describes the true ratio of atoms in a formula unit. An empirical formula is a formula that gives the proportions of the elements present in a certain compound however it does not give the actual numbers or the arrangement of the atoms.

What are physical and chemical properties of boron?

Elina [12.6K]

The chemical properties of boron are more similar to carbon and silicon than elements of its own group, although boron is more electron deficient. Boron has a high affinity for oxygen-forming borates, and reacts with water at temperatures above 100 °C to form boric acid and other boron compounds.”
