The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...
If the number of in an atom is changed, it is no longer the same element. a) proton b) neutron c) electron Two atoms of the same element with the same number of protons, but different numbers of neutrons are called (a) __...
NeutronSourceThermal neutron capture can be used as a successful technique for detection of non-metallic landmines via the detection of their constituent like nitrogen. Recently, it has been shown that the detection of 10.829 MeV photons from the 14N(n,纬)15N reaction can be used for finding ...
For example, the final state in neutron β-decay (i.e., n→pe−ν―e) has Le=Le(p)+Le(e−)+Le(ν―e)=(0)+(1)+(−1)=0 like the initial state, which has Le (n) = 0. The value of each lepton number is conserved in any reaction. In electromagnetic interactions, ...

The number of protons and neutrons is known as the ___. Elements are ordered in the periodic table by their: A) atomic number or proton and neutron number. B) atomic number or electron number. C) atomic number or proton number. D) ...
To find the sum of the number of neutrons and protons in the isotopes of hydrogen, we will follow these steps:Step 1: Identify the isotopes of hydrogen Hydrogen has three main isotopes: 1. Protium (¹H) 2. Deuterium (²H) 3

The atomic number of an element is equal to the number of protons in its nucleus. In a neutral atom, the number of protons equals the number of electrons in shells which is the energy level around the nucleus. Isotopes are atoms with the same atomic number but distinct neutron numbers, ...
