The diameter of a proton is about 1 × 10 - 12 mm. Write this number in standard form. => 0.00000000001 or 0.0000000001 or 0.0000000000001 or 0.000000000001..
Nuclear Stability and Neutron/Proton Ratio
neutrons number against the atomic number for a range of stable nuclei Nuclear Stability and Neutron/Proton Ratio - It has been found that the stability of nucleus depends upon its neutron to proton (n/p) ratio. A plot of N (the neutron number) against Z (atomic number or number of protons) show that for stab..

Atomic Number
The number of protons or the number of electrons in an atom in its normal state is called the atomic number and is denoted by Z. The nucleus of every element contains Z protons and some number of neutron..
Mass number
symbolic representation of an atom The sum of the number of protons and neutrons in the nucleus of an atom is called the mass number. It is represented by the letter A. Mass number (A)= Number of protons (p) + number of neutrons (n) From the knowledge of atomic h..

Atomic Number and Atomic Mass
The nuclei of atoms is made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the number of protons in the nucleus is exactly equal to ..
Relation between Mass Number and Atomic Number
Atomic Number (Z) is the number of protons in the nucleus of an atom. It is also equal to the number of electrons since the atom is electrically neutral. Mass Number (A) is the total number of neutrons and protons present in the..

The nuclei of atoms are made up of protons and neutrons. These two components of the nucleus are referred to as nucleon..
Oxidation Number
>Each hydrogen atom is having one electron while its nucleus has one proton and so there is no net charge on each atom of hydrogen. The oxidation number of hydrogen in hydrogen molecule is zero. Electrons shared between two unlike atoms are counted with more electronegative atom..

Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
I think the tutors knew their stuff really well and was very helpful. math was actually something I dread.not anymore ,Thank you Tutor Vista - jennifer,New york
