The two words that best describe me? Solid gold. In fact, I'm made up of a single element. I existed as shiny flakes on other rocks, but was eroded by wind and water. Because I was so heavy, I sank to the bottom of a stream. Then people scooped me up and melted me into a big old block of gold.​

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

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.
