How many neutrons does an atom of Na have if its atomic number is 11 and its mass number is 23?

How many neutrons does an atom of Na have if its atomic number is 11 and its mass number is 23?

12 neutrons
For sodium, that means there are 11 protons and 11 electrons. Since we know that there are 11 protons, there must be 12 neutrons for the mass number to equal 23 (23-11=12).

What atom has 11 protons 11 electrons and 12 neutrons?

sodium atom
The sodium atom contains 11 electrons, 11 protons, and 12 neutrons.

How many protons neutrons and electrons are in sodium 11?

An atom of a sodium has 11 protons, 11 electrons, 12 neutrons.

How many electrons are in an atom of elemental sodium equal to the number of neutrons equal to the number of protons equal to the number of protons and neutrons?

11 electrons
In order for the atom to remain electrically neutral the protons and electrons must balance each other. Sodium has 11 protons 12 neutrons and 11 electrons. Sodium has 17 protons 18 neutrons and 17 electrons.

What is the relationship between an atom containing 11 protons?

Isotopes are defined as atoms of same element having the same atomic number, but different mass numbers. These atoms contain an equal number of protons and electrons, but a different number of neutrons. Q3. An atom of an element has 11 protons, 11 electrons and 12 neutrons.

What is the atomic number of a sodium atom with 11 protons and 12 neutrons?

23
Protons and neutrons have similar masses, approximately 1 amu each. Most sodium atoms have 11 protons and 12 neutrons, giving a total of ~23 amu, and dividing by 1 amu then gives 23 for the relative atomic mass.

What contains exactly 11 protons?

sodium
Any atom that contains exactly 11 protons is an atom of sodium.

What is the atomic mass of sodium if it has 11 protons 11 electrons and 12 neutrons?

The mass number is 23.

What is relationship between an atom containing 11 protons 11 electrons and 11 neutrons and another atom containing 11 protons 11 electrons and 12 neutrons?

What is the relationship between an atom containing 11 protons, 11 electrons and 11 neutrons, and another atom containing 11 protons, 11 electrons and 12 neutrons? As the number of electrons and protons are the same but the number of neutrons is different, these atoms are isotopes of each other.

What is the atomic number of an atom which contains 11 protons 11 electrons and 6 neutrons?

Explanation: Sodium has an atomic number of 11.

What is the atomic symbol for an atom with 11 protons and 12 neutrons?

Z specifies the identity of the nucleus. If Z=11 , then the element is sodium. We would thus describe this species as 23Na .

What is the mass of an atom which has 11 protons and 12 neutrons?
