Sodium, which has an atomic number of 11, will react with chlorine, which has an atomic number of 17. when these two atoms react, both become stable. to become stable, sodium will while chlorine will

Explanation:

Atomic number of sodium is 11 and its electronic distribution is 2, 8, 1. Whereas atomic number of chlorine is 17 and its electronic distribution is 2, 8, 7.

As we known that in order to attain stability each element must have 8 electrons in its outer orbital. Therefore, in order to attain stability sodium will lose one electron and chlorine will tend to gain one electron.

As a result, an ionic bond will be formed between sodium and chlorine and hence, NaCl is formed.

Thus, we can conclude that sodium, which has an atomic number of 11, will react with chlorine, which has an atomic number of 17. when these two atoms react, both become stable. to become stable, sodium will lose, while chlorine will gain an electron.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
