Atomic Number The total number of unit positive charges present in the nucleus of an atom is known as its Atomic Number which is equal to the number of protons in the nucleus of an atom. Atomic Number for any two different atoms is never same and hence can be used to distinguish two ...
Number of neutrons in the nucleus of the Sodium ion = 12 The atomic mass of Sodium $=11+12=23$ Hence, 1 mole of Sodium weighs 23 grams.We know,Since the atomic mass of Sodium is 23, we can also write it as 23 g/mol.Therefore, we conclude that...
Each12C atom has six protons and six neutrons in its nucleus, adding up to an atomic mass of 12 AMU.Electronshave a low mass, so they are assumed to have a negligible effect. Consequently, the nucleus accounts for almost the entire mass of the atom of any element, which means that a ...

To understand the relationship between atomic mass and the actual mass of one atom of an element, let's break it down step by step. Step 1: Define Atomic MassAtomic mass is defined as the mass of one mole of atoms of an element, which is equivalent to Avogadro's number (approximately ...
What is the difference between atomic structure and crystal structure? What makes up most of the volume of an atom? How does an ion differ from an atom? What are the masses of the subatomic particles? What is the mass number for silicon?
What Is Atomic Mass [/caption] The answer to ‘what is atomic mass’ is this: the total mass of the protons, neutrons, and electrons in a single atom when it is at rest. This is not to be associated or mistaken for atomic weight. Atomic mass is measured by mass spectrometry. You ...
