number of neutrons for chlorine

The whole mass of an atom is due to the nucleus, which means that the nucleus must contain protons equal to the mass of the atom. As the number of protons is equal to the atomic number, the atomic mass should be equal to the atomic number. But for all atoms except hyd..

(ii) The neutrons can be absorbed by substances which are not fissionable. Rods of boron or cadmium have the ability to absorb the desired number of neutrons. This ensures limited number of neutrons to be available for fission. (iii) The speed of t..

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..

Symbol Cl Formula cl2 Atomic number 17 Electronic configuration 2, 8, 7 Valency -1 Relative Atomic Mass 35.5 Relative Molecular Mass 71 Vapor Density 35.5 Isotopes 35 37 Cl , Cl17 ..

The 1 st electron-affinity of chlorine is - 3.64 × 10 2 kj/mole. Write this number in standard form. => - 364000 kj/mole or - 364 kj/mole or - 36400 kj/mole or - 3640 kj/mole..

The nuclei of atoms are 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 the ..

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 neutrons..

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 neutrons. The electrons, having the same charge as a ..

>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. For exam..

The total number of protons and neutrons present in one atom of an element is known as its mass number. Mass number = number of protons + number of neutrons It can also be said that: Mass number = Atomic number..
