What will happen if a piece of silver metal is placed in a solution of zinc nitrate?

Zinc is above silver is the metal reactivity series, so it will replace silver in silver nitrate.

Explanation:

This single replacement reaction will produce silver metal, Ag , and aqueous zinc nitrate, Zn(NO3)2 . Zinc is above silver is the metal reactivity series, so it will replace silver in silver nitrate. Notice that this is also a redox reaction.

If you still don't understand, tell me! :)

distance, luminosity, brightness, radius, chemical composition, and temperature

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
