Answer:
5 valence electrons
Nitrogen has a total of 5 valence electrons
Explanation:
Explanation:
A chemical bond which is formed in between positively charged atoms when there is sharing of free electrons in a lattice of cations is known as a metallic bond.
In a pure metal, atoms are surrounded by free moving valence electrons which move from one part of metal to another.
Thus, we can conclude that pure metals are held together by metallic bonds due to attraction between mobile valence electrons and positively charged metal ions.
Answer:
Explanation:
Hello.
In this case, since the neutralization of the acid requires equal number of moles of both acid and base:
Whereas we can express it in terms of concentrations and volumes:
Thus, we can compute the volume of sodium hydroxide (base) as follows:
Best regards.
PH is an important quantity that reflects the chemical conditions of a solution. The pH can control the availability of nutrients, biological functions, microbial activity, and the behavior of chemicals.
