Scot has a 50 g sample of sandstone. the sandstone is formed by sedimentation, compaction, and cementation of 50-g of sand particles. based on this information, what can scot conclude?

it is a good conductor

explanation:

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.  

the answer is c

tell me if wrong

the answer is 0.42 is that is an option. this question provides no info
