Answer:

Element is made up of the atoms or isotopes. Isotopes are where only neutrons change in number, such as 3 turning to 2 or to 5. Atom is where it is not changed and it is the original, and example is instead of Carbon13 it is just Carbon. I hope this helps.

Answer:

Isotopes are atoms that have the same numbers of protons but different numbers of neutrons. An ion is an atom that has gained or lost electrons, so it now has more or fewer electrons than it does protons. So an ion has a negative or positive charge.

Explanation:

it does

Which of the following elements will gain electrons to form an
blsea [12.9K]

Answer:

F

Explanation:

When an atom lose or gain electrons ions are formed.

There are two types of ions. Cation and anion.

Cation:

Cations are formed when atom lose electrons. For example:

X → X⁺ + e⁻

Anion:

It is formed when an atom gain electrons. For example:

X + e⁻  → X⁻

Fluorine is present in group seventeen. It has seven valance electrons. It gain one electron to complete the octet and form anion with charge of -1.

Calcium is alkaline earth metal. It is present in group two it loses two valance electrons and form cation with charge of +2.

Neon is noble gas. It already have complete octet. It can not form ions. To remove the electrons from noble gases very high temperature is required.

Zinc is present in group 12. It usually form cation by losing its two valance electrons but it can also show oxidation state -2.

22<br> Which of these best describes atoms of the same element?
Misha Larkins [42]

An atom consists of three sub atomic particles which are protons, neutrons, and electrons. ... This nucleus is surrounded by the electrons as electrons revolve around the nucleus. Thus, we can conclude that out of the given options, a core of protons and neutrons surrounded by electrons best describes an atom.
