The mass number would be 23 and the atomic number 11 making it sodium.
What else can I help you with?
What is atomic mass A and neutron number N for given atom?
Atomic mass is the number of protons and neutrons that make up an atom. The neutron number is only the number of neutrons present in the atom. This can be found by subtracting the number of protons from the atomic mass.
The diffirentiate of atomic mass and atomic number?
Atomic mass is defined as the sum of the no. of proton and neutron present in the nucleus of an atom and Atomic Number is defined as the no. of electrons present in the extra nuclear part of an atom . BY; SHUBHAM KAKKAR
How do you determine the number of neutron?
Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number *A note on Atomic Mass* Atomic Mass is the sum of the number of protons and neutrons in an atom. Every time you remove or add a Proton/Electron or a Neutron, you change the mass by one. *A note on Protons and Electrons* The number of Protons and Electrons in an atom is always the same. Whenever you talk about adding/removing a proton or an electron, you are by default adding/removing one of the other as well.
What is the mass number of the atom if the protons and electrons are both 29 and the neutron is 35?
This isotope is copper-64.
What is the mass of a proton is approximately equal to the mass of?
The mass of 12 protons is approximately equal to 12 atomic mass units.
How do you determine an atom's mass number?
mass number= no. of protons + no. of neutron
What is atomic mass A and neutron number N for given atom?
Atomic mass is the number of protons and neutrons that make up an atom. The neutron number is only the number of neutrons present in the atom. This can be found by subtracting the number of protons from the atomic mass.
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
The sum of the number of protons in the number of neutrons in and Atom is the what?
The number of protons plus the neutron number is called the atomic mass or "mass number".
Is the atomic number of an atom equal to its number of protons and the atomic mass is equal to its number of neutron Protons?
yes
The mass number of an atom is found by adding the?
The mass number of an atom is found by adding the number of protons and neutrons in its nucleus. It is an integer value that represents the total number of nucleons in the atom.
What is mass number if atom has 31proton 39neutrons 31electrons?
neutron plus protons = mass number cesium
What is the mass number of an atom with 11 protons 11 electron and 12 neutron?
The mass number of an atom is the sum of the number of protons and neutrons in the nucleus. In this case, the atom has 11 protons and 12 neutrons, so the mass number would be 11 + 12 = 23.
What is mass number equal to?
The mass number of an atom is defined as the total number of protons and neutron (collectively called "nucleons") in the atomic nucleus. For example, a helium atom with 2 protons and 2 neutrons would have a mass number of 4.
What has mass in atom?
i think it's Neutron and protons
How does a neutron have same number of protons and electrons?
a neutron is neutral. it doesn't have the same number of protons and electrons, but an atom that is neutral does. A neutron has the same mass as a proton but it doesn't have a chrge. Protons are positively charged and electrons are negatively charged.
What does the Mass number in chemistry represent?
The mass number in chemistry represents the total number of protons and neutrons in an atom's nucleus. It is used to identify isotopes of an element, where different isotopes have the same number of protons but a different number of neutrons.
