In an element, the numbers of electrons and protons are equal. Moreover, since they have opposite charges, they cancel each other out and keep the atom neutral. The total number of protons present in the atom of a substance is known as theatomicnumber. Atomic mass refers to a weighted a...

If an atom has an atomic number of 8, how many protons will it have? What is darmstadtium's atomic mass? What is effective atomic number? Is the atomic number equal to the number of electrons? What is the atomic mass of helium-4?
An atom has a mass number of 24 and 13 neutrons. what is the atomic number of this atom?Atomic and Mass Numbers:The atomic number of an atom is equal to the number of protons found in the atom's nucleus. The mass number of an atom is the total number...
If an atom of an element has twice the mass of C-12 , then its atomic mass will be nearly View Solution The ratio of the mass of a sulphur atom to that of an oxygen atom is 2:1. If the molar mass of O atoms is 16gmol−1 find the mass of one mole of S atoms View Solutio...
The wavelength of the de-Broglie wave associated with a thermal neutron of mass m at absolute temperature T is given by (here, K is the Boltzmann constant) View Solution What is the de Broglie wavelength of a 2 kg mass moving with a velocity of 10 m/s?
one can build atom interferometers using matter “reflected” off of pulses of light. Such atom interferometers have the benefit that the atoms themselves have mass, making them sensitive to both gravity and general acceleration. Accordingly, there is an emerging area of work onquantum-enabled “PN...
That’s twice the density of lead or about 8 times that of granite. A cube 6 inches on a side (15 cm) of either would weigh as much as an average adult human. Ag Rh Pd Au Pt Re Ir Os Density (g/cm3) Some of the superheavy elements will probably turn out to be much denser...

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...
