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 ...
To solve the question regarding the changes in atomic number and mass number when different types of radiation are emitted from a nucleus, we will analyze each case step by step.1. Emission of an Alpha Particle: - When an al
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 ...
An atom has a mass number of 24 and 13 neutrons. what is the atomic number of this atom? An atom has a mass number of 25 and 13 neutrons. what is the atomic number of this atom? An atom has an atomic number of 12 and a mass number of 25. how many neutrons does th...
Atomic Number: The atomic number of an element defines it and is equal to the number of protons in the nucleus. Protons: Protons are positively charged subatomic particles that make up the nucleus. Neutrons: Neutrons are neutrally charged subatomic particles that along with protons, make up the...
Consider the element Au (Atomic Mass = 197). How many protons, neutrons, and electrons does a neutral atom have? An element has an atomic number of 114 and an atomic mass of 285. How many protons, neutrons, and electrons does a neutral atom of this element have?

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 ...
