Question 5 of 5 A student studies how an object's mass and speed are related to its kinetic energy. The table shows the results for one part of the investigation. ? Kinetic energy (J) 1 100 2 200 3 300 Which two terms are most likely to be used to label the data in the first column? A. (m/s) B. Speed C. (kg) D. Mass

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.
