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...
An atom consists of a nucleus and an electron cloud around it. Nucleus consists of protons and neutrons. A neutral atom has equal number of protons and electrons. The number of protons plus the number of neutrons is the mass number of the atom....
Atomic Number: The atomic number of an element represents the number of electrons or the number of protons in the element while the atomic mass represents the sum of neutrons and protons that exist in the element. Answer and Explanation:
Polonium has few applications, and those are related to its radioactivity: heaters in space probes, antistatic devices, sources of neutrons and alpha particles, and poison. It is extremely dangerous to humans. langbot Heading N° 2844 applies only to : (a) technetium (atomic N° 43), ...
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 atomic number of gold is 79 and the mass number of one of its isotopes is 197. The number of neutrons is (a) 79. (b) 197. (c) 118. (d) 158. Uranium 235 has 92 protons in its atoms. Calculate the number of neutrons in this atom. ...
