Neutron has neutral charge (0) and located in nucleus
Chemical reaction is the basis of life for living organisms; no organism can remain alive without the occurrence of chemical reactions.
Chemical reactions that occur in the living organisms are called biochemical reactions, these reactions are needed for the organism to grow, develop, survive and remain alive; when the chemical reactions stop the organism die.
For instance, to remain alive one has to eat. The food eaten can not be useful to the body if the digestive enzymes do not carry out chemical reactions on it and convert it to a form that can easily enter the blood where it is needed.
<u>Answer:</u> The chemical symbol of the compound formed is 
or 
<u>Explanation:</u>
An ionic compound is formed when the complete transfer of electrons takes place from one element (usually metals) to another element (usually non-metals).
The element losing electron (metal) forms a positive ion known as a cation while the element gaining electron (non-metal) forms a negative ion known as an anion.
Element X has the atomic number 11 which is sodium. The electronic configuration of it is 
This element will lose 1 electron to form 
ion of 
Chlorine has the atomic number 17. The electronic configuration of it is 
This element will gain 1 electron to form 
ion
When these two ions combine, they lead to the formation of an ionic compound having a chemical formula of or
Hence, the chemical symbol of the compound formed is or
