1.

The two ways which one carbon atom can differ from another are:

1) Number of neutrons in the nucleus of the atom
2) Atomic mass of the atom

The 3 ways in which all carbon atoms differ from all uranium atoms:

1) Atomic mass. Carbon’s atomic mass is 12.01, while uranium’s atomic mass is 238.03
2) Half lives.
3) Number of protons, neutrons and electrons.

2.

The numbers beside the two ‘N’s indicates the atomic mass of 2 different Nitrogen atoms. Not all nitrogen atoms have the same atomic mass, which results in these 2 nitrogen atoms having different numbers to represent them. The term, isotope, is used to describe the different variety of atoms of the same element.

In addition, since the atomic mass are different, their nuclear reaction and properties would be different as well. Hence, these 2 representations are important as it is a way to distinguish the different isotopes of the same element.

1. Carbon atoms can differ in their number of neutrons: C-12 and C-14 are naturally occuring isotopes. Proton, neutron and electron number
2. 14N and 15N are isotopes of nitrogen. This would give details about their slightly different physical and chemical properties. 14N: 7 protons, 7 neutrons, 7 electrons. 15N: 7 protons, 8 neutrons, 7 electrons. Symbol N just tells us that it is an element nitrogen with no physical properties or alternative forms stated.

1. The two ways are: 1) Carbon -12 and Carbon-14 (difference in the number of neutron for each) 2) Arranged differently ( i.e Diamond and graphite Three ways carbon atoms differ from all uranium atoms: 1) different atomic number (carbon-6 and uranium-92 2) Different atomic weight (carbon-12 and uranium-288) 3) Carbon: usually found in life form Uranium: creating atomic energy from ‘nuclear fission’
2. The symbol N means the element Nitrogen 14N and 15N are naturally occurring mixture of nitrogen isotopes. Isotopes are same element that contains different number of neutrons but same number of protons. Thus 14N and 15N have specific mass number (protons+neutron). Therefore, they are both isotopes of nitrogen

1. 2 ways which one carbon can differ from another – The way the carbon are arranged in space. E.g. Diamond is tetrahedral whereas graphit has infinite array layer – Carbon isotopes, they have the same number of protons but different number of protons. 3 ways which carbon atoms differ from uranium atoms – Atomic number of carbon is 6 whereas for uranium is 92 -Atomic weight of carbon is 12 whereas for uranium is 238 – Carbon isotopes are mostly stable whereas uranium isotopes are usually radioactive.
