Which of the following correctly shows the relationship, in terms of number of particles, of the three substances? A. 1 mole of water < 1 mole of helium < 1 mole of aluminum

B. 1 mole of aluminum = 1 mole of helium = 1 mole of water

C. 1 mole of aluminum < 1 mole of helium < 1 mole of water

D. 1 mole of helium < 1 mole of aluminum < 1 mole of water

the answer to your question is c

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.  

2b2t

explanation:

2b2t

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
