Jill tells bobby that the lightest element in the periodic table is chlorine because it has an atomic number of 17. bobby states that jill is incorrect and that he believes that hydrogen is the lightest element because it has an atomic number of 1. which statement is correct? question 4 options: jill is correct because chlorine has more protons. bobby is correct because chlorine has more protons.

Hydrogen is the lighest element in the periodic table.

Explanation:

Hydrogen is known by being the lights element with an average atomic mass of 1. Hence, Bobby is correct.

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
