The mass number is the sum of protons and neutrons in an atom. In this case, the atom has 11 protons and 12 neutrons, so the mass number is 11 + 12 = 23.

An atom has 15 protons and 18 neutrons How many electrons does it have?
An atom with 15 protons has 15 electrons to balance the charge. The number of neutrons does not affect the number of electrons in an atom.
How many electrons does a chlorine atom have if it has 17 protons and 18 neutrons?
A chlorine atom with 17 protons will also have 17 electrons to maintain neutrality. The number of neutrons (18) does not affect the number of electrons in an atom.
How many protons neutrons and electrons are there in a gold atom?
A gold atom typically has 79 protons, 118 neutrons, and 79 electrons.
How many electrons would you expect to find in a neutral atom containing three protons and four neutrons?
In a neutral atom, the number of electrons is equal to the number of protons. So, in an atom with three protons, it would contain three electrons. The number of neutrons does not affect the charge or number of electrons in the atom.
A certain atom has 8 protons and 10 neutrons. How many electrons does it have?
The number of protons in an atom is equal to the number of electrons. Therefore, an atom with 8 protons will have 8 electrons.
An atom has 15 protons and 18 neutrons How many electrons does it have?
An atom with 15 protons has 15 electrons to balance the charge. The number of neutrons does not affect the number of electrons in an atom.
How may electrons neutrons protons are foundin the helium atom?
In a helium atom, there are 2 protons, 2 neutrons, and 2 electrons. This gives helium an atomic number of 2 and a mass number of 4.
An atom has what number of protons and electrons?
An atom has the same number of protons as electrons since they are electrically neutral.
What are the Number of protons neutrons and number of electrons found in an atom of neon?
Neutrons = 10. Protons = 10. And electrons = 10.
How many protons electrons and neutrons does an atom have?
Americium has 95 protons and electrons. Number of neutrons: Atomic Mass of an isotope - number of protons
What particles make up the mass of an atom?
The number of protons
Is an atom that has the same number of protons as neutrons a neutral atom?
No, an atom with the same number of protons as neutrons is not necessarily a neutral atom. Neutrality depends on the number of electrons, which must balance the positive charge of the protons.
How do you find the number of electrons in an atom if you know the number of protons and neutrons?
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
How many electrons does a chlorine atom have if it has 17 protons and 18 neutrons?
A chlorine atom with 17 protons will also have 17 electrons to maintain neutrality. The number of neutrons (18) does not affect the number of electrons in an atom.
Is the number of electrons equal the number of neutrons in an atom?
not usually, a standard atom will contain the same amount of electrons and PROTONS, not neutrons
What are the Number of protons neutrons and number of electrons found in an atom of oxygen?
An atom of oxygen has 8 protons, 8 neutrons, and 8 electrons. The number of protons determines the element's identity and is equal to the atomic number, while the number of neutrons can vary, leading to different isotopes. The number of electrons is equal to the number of protons in a neutral atom.
How many protons neutrons and electrons are there in a gold atom?
A gold atom typically has 79 protons, 118 neutrons, and 79 electrons.
