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.
Answer:a reddish- or yellowish-brown flaky coating of iron oxide that is formed on iron or steel by oxidation, especially in the presence of moisture.
Explanation: so basically rusting happens when a metal comes in contact with moisture and air, at a brown, dirty metal coat forms on it.
