What is the mass number of tritium? What is the atomic number for californium? How many neutrons are there in an atom of lead whose mass number is 208? What is the atomic mass of helium-4? What is the mass number of argon?
What is the atomic number of mercury? What is the atomic number of chromium? Calculate the number of neutrons in a bromine nucleus, which has a radius of approximately 5.38 x 10-15 m. The atomic number of carbon is 6, the atomic number of chlorine is 17, and the atomic number of bro...
Atomic number Z represents the number of protons per atom. 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 ...

The number of protons in the nucleus is called the atomic number. The atomic number of each element is unique. The combined number of protons and neutrons in an atom is called the atomic mass number. While theatomic numberalways stays the same. Some elements have atoms with different atomic...
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. The number of protons determines the element, but the number of neutrons in the atom of any one element ...
Write the ground-state electronic configurations for the valence shell electrons of C, O, S, Cl, and Ni showing schematically the spins of electrons in each orbital. Indicate the number of protons and the number of neutrons in each of the following nuclides:...
In stead of a single wire when two different material wires are joined to form a by junction circuit and the junctions are maintained at different temperatures, higher potential difference is developed across the junctions. The arrangement of two different metal wires to form by junction is known...
