If solid ice with a temperature of -10°C is added to the cup of room temperature salt water, do you expect the minimum temperature that can be reached by the salt water to be 0°C, more than 0°C or less than 0°C

1. they vary with a higher number because boiling is way hotter than melting

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.
