The formula of ionic compound made from sodium (Na) and iodine (l) is
NaI
<em><u>Explanation</u></em>
- An ionic compound is are compounds made up of ions.
- The ions are atoms or ions that loses electron to form cation or gain electron to form anion.
- Metal for this case loses electron while non metal gain electrons
- In Nal Na <em>( a Metal</em>) loses one electron while I <em>(non metal) </em>gain one electron to form an ionic compound.

Answer:
Option E
RbCL<CH3OH< CH3Cl< CH4
Explanation:
The boiling temperature of an organic compound increases with the increase in number of carbon atoms and hence as the length of the hydrocarbon chain increases the boiling temperature also increase due to increase in force of attraction between the molecules. Also presence of strong molecules such as OH – COOH also increases the boiling temperature while Cl and other elements with high electronegativity reduces the boiling temperature
Hence, the correct order of increasing boiling temperature is option E
RbCL<CH3OH< CH3Cl< CH4
Answer:
A. Protons are positive and carry a charge of +1
B. Neutrons are neutral so carry a charge of 0
C. Electrons are negative and carry a charge of -1
