The weight of an electron is almost negligible. Thus, the atomic mass of an atom is almost the same as its mass number. History of Atomic Number We take the existence of atoms for granted – yet for centuries no one believed in them. Around 2500 years ago a Greek philosopher called Leuc...
Atoms contain three types of subatomic particles called protons, neutrons, and electrons. Protons carry a positive charge and are found in the nucleus of an atom. The mass of a proton is 1.6726219 × 10-27 kilograms.
Molecular mass- Well, each of the atom of a molecule has an atomic mass. But when it comes to molecules, elements other than the noble gases, have more than one atom and therefore there arises a confusion. For example, Oxygen is a diatomic element and has 2 atoms in one molecule. ...
The atomic mass of an element is an average of the mass number for every atom of that element, including those of all the isotopes. Answer and Explanation: 1 Become a Study.com member to unlock this answer! Create your account View this answer The mass number of nickel is 58. This...
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...

A. Calculate the number of moles of gold in the sample. B. Calculate the number of atoms of gold in the sample. Gold: Gold (Au) is a transition metal with an atomic number of 79. It is one of the least reac...
The numerical value for the mass of one mole (molar mass) of an element’s atoms is the same as the value for the mass of an individual atom of that element (atomic mass); however, the units on these mass numbers are different. An element’s molar mass can be used to calculate the...
How does the mass of a nucleon differ with the mass of an electron? Atom and Subatomic Particles An atom is considered as the smallest particle of a chemical element that is existing in nature. All substances are made up of either neutral atoms or ionized atoms. The atoms of all...
