The Atomic Number of an element is equal to the number of Protons/Electrons in the nucleus and the Atomic Weight is approximately the total number of Protons/Electrons and Neutrons combined. Using Carbon as an example: Total Protons/Electrons = 6, therefore the Atomic Number is 6
Total Neutrons = 6, and the Atomic Weight is 12 Question? The Atomic Number of Lithium = 3
The Atomic Weight of Lithium = 7 How many Protons/Electrons?
How many Neutrons? Answer: Protons/Electrons = 3
Neutrons = 4
Atomic mass is how much it weighs, the atomic number is how many protons/electrons it has
The isotope number refers to the total number of protons and neutrons in the nucleus of an atom of a specific element. It is used to distinguish between different isotopes of an element based on their atomic mass.
Calcium has atomic number of 20, an atomic weight of 40.078 and an mass numbers of 40 - 48 inclusive in its isotopes. Atomic number is the count of protons in the nucleus. Mass number is the count of protons plus neutrons. The question refers to atomic mass rather than atomic weight. Atomic mass normally refers to the mass of a specific isotope of an element and is related to the mass number. Atomic weight ( or relative atomic mass as it is termed by IUPAC) the average mass of naturally occurring isotopes of an element. The relationship between mass number and atomic mass is defined in terms of the Atomic mass unit which is in simple terms 1/12 of the mass of a 12C atom. If you need to find out more about the relationship between mass number and and atomic mass you need to read the article "atomic mass unit" in wikipedia.
Mass number is the total number of protons and neutrons in an atom's nucleus. Atomic mass is the average mass of an element's isotopes taking into account their relative abundance. Atomic number is the number of protons in an atom's nucleus, which determines the element's identity.
Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
mass number=atomic number+no. of neutrons
Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
It is equal to the difference between atomic number and Atomic Mass number. A+
Atomic number is the amount of electrons. Atomic mass is the amount of protons and neutrons.
Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
Atomic mass is how much it weighs, the atomic number is how many protons/electrons it has
Atomic number shows the number of protons in an element and the mass number shows the number of protons+neutrons In an electrically neutral atom, atomic number is also the number of electrons .
Atomic number is the number of protons. Mass number is the total of protons and neutrons.
Atomic Mass is the mass of an atom in Atomic Mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
Atomic Mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
