Atomic number depends on the number of protons and it doesn't matter how many neutrons there are in that case. Neutrons only contribute to the atomic weight. The atomic number is the same as any other atom of carbon: 6.

An atom that has twelve protons in its nucleus has an atomic number of?
atomic number is always equal to number of protons. Thus, the atomic number of the element is 12.
How many electrons are in a magnesium atom?
12The atomic number of Mg is 12. This means it has 12 protons in the nuclei of its atoms. In a neutral atom, the number of electrons equals the number of protons.12
The atomic number of an atom is equivalent to which of the following?
The atomic number of an atom is equivalent to the number of protons in its nucleus.
What do you get if you subtract the atomic number from the mass number for a particular atom?
mass no - atomic no = number of neutrons in an atom.
A sodium atom has a mass number of 23 Its atomic number is 11 How many electrons does it have if it is not an ion?
it is 12
What is the atomic number and mass number of an atom with 11 protons and 12 neutrons?
Its atomic number is 11 and its mass is 22.99. This atom is a sodium atom.
Atom has a mass number of 25 and 13 neutrons. What is the atomic number of this atom?
12
If the atom has 14 protons and 12 neutrons what the atomic number?
The atomic number is 14 - silicon.
An atom that has twelve protons in its nucleus has an atomic number of?
atomic number is always equal to number of protons. Thus, the atomic number of the element is 12.
What is the atomic number of magnesium what does the number tell you?
The atomic number of magnesium is 12. The atomic number is equivalent to the number of protons and electrons in the atom.
How many protons are in an atom that has an atomic number of 12 and a mass number of 22?
12
if an atom has a mass number of 32 and it has 20 neutrons in the nucleus, what is the atomic number of this atom?
12 protons
What is the number of neutrons in an atom with atomic number 12 and mass number 22?
Number of neutrons = Mass number - Atomic number = 22 - 12 = 10
An atom of the element has an atomic number of 12 and an atomic of weight 24 How many electrons does it have?
It will have 12 electrons.
What is the atomic number of an atomic indicate?
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
What is the atomic number and the mass number of an atom of an element with 11 protons and 12 neutrons?
Atomic number: 11 Mass number: 23 (11 protons + 12 neutrons) Atomic mass (aka atomic weight): 22.98976928 Element: Sodium (sodium-23 is the only stable sodium isotope)
Distinguish between atomic number and atomic mass?
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
