Answer:
Neutrons.
Explanation:
Isotopes can be defined as the atom of an element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic mass (number of nucleons).
The isotope of an element is denoted by
Where; X is the symbol of the element.
A is the atomic mass or number of nucleons.
Z is the atomic number or number of protons.
<em>Therefore, the number of neutrons = A - Z</em>
<em>Isotopes of carbon differ with respect to the number of neutrons.</em>
<em>Basically, there are three (3) Isotopes of Carbon and these are;</em>
<em>1. Carbon-12: it has an atomic mass of 12 with 6 numbers of proton and neutron respectively. </em>
<em>2. Carbon-13: it has an atomic mass of 13 with 6 numbers of proton and 7 numbers of neutron. </em>
<em>3. Carbon-14: it has an atomic mass of 14 with 6 numbers of proton and 8 numbers of neutron. </em>
CH3COH(CH3)2; (CH3)3COH is the answer. Please let me know if this helps.

Look at my answer to the last one, and see if you can solve this one on your own!
After you try it, I can let you know if you got it right :)
Answer: a. alpha emission : atomic number decreases by 2 units and mass number decreases by 4 units.
b. beta emission : atomic number increases by 1 unit and mass number remains same.
c. gamma emission : atomic number and mass number both remain same.
Explanation:
1. Alpha emmision: In this process, alpha particles is emitted when a heavier nuclei decays into lighter nuclei. The alpha particle released has a charge of +2 units, thus atomic number decreases by 2 units and mass number decreases by 4 units.
2.)Beta-emmision: In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units, thus atomic number increases by 1 unit and mass number remains same.
3.) Gamma ray emission: in this process, an unstable nuclei gives off excess energy by a spontaneous electromagnetic process and releases . These radiations does not carry any charge and are electrically neutral, thus atomic number and mass number both remain same.
