In heavy hydrogen (.(1)H^(2)) number of neutrons = Mass No. - At. No. = 2 - 1 = 1.
⇒ mass of number (A)=Atomic number (Z)+ Number of neutrons (n) ⇒A=Z+n Number of neutrons in nucleus We know A=Z+n⇒n=A−Z A,B and C are the number of neutrons in hydrogen, helium and lithium. A+B+C= View Solution ...
Mass number Z + N is equal to the number of protons Z plus the number of neutrons N present in the nuclei. Mass numbers of the most abundant isotopes are given in order of decreasing abundance. For example, Cadmium Cd-48 mass numbers 114-112 means that cadmium atoms of greater abundance...
Its nucleus also contains two neutrons. Hence, 2+2=4, which gives the mass number of the helium atom. As the number of protons must equal the number of electrons, there are two electrons in the helium atom. Similarly, lithium has three protons and four neutrons and a mass number of 7...
The nuclear notation of an atom or an ion shows the number of protons, the number of neutrons, and sometimes, the number of electrons. However, these are not presented as they are because they are encoded as the mass number and the atomic number. With this, it is easier ...
What is the atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons? What is the atomic number of rubidium? What is the atomic number of oxygen? What is the atomic number of roentgenium? What is the atomic number of aluminium?
The only factor that can enhance the bonding caused by the nuclear factors is the third factor in reverse, i.e., when an even number of neutrons and protons are present. These trends combined tend to favor an increasing neutron/proton ratio for high mass number nuclides, and equal number ...
Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element...
