What is the mass number of the atom that has 11 protons 11 electrons and 12 neutrons?
The mass number of an atom is the sum of protons and neutrons in the nucleus. In this case, the atom has 11 protons and 12 neutrons, so its mass number would be 11 + 12 = 23.
What is the mass number of an atom with 11 protons 11 electrons 12 neutrons?
Sodium is a metal element. Mass number of it is 23.
An atom of boron (B) has 5 protons and 6 neutrons. What is its mass number?
The mass number of an atom is the total number of protons and neutrons in its nucleus. Therefore, the mass number of boron with 5 protons and 6 neutrons is 11.
If the sodium atom contains 11 electrons 11 protons and 12 neutrons what is the mass number of sodium?
The mass number of an atom is the sum of its protons and neutrons. In this case, sodium has 11 protons and 12 neutrons, so the mass number is 11 + 12 = 23.
What is the atomic mass number of an atom of sodium that contains 12 neutrons?
The atomic mass number of an atom is the sum of its protons and neutrons. Sodium typically has 11 protons, so if the atom has 12 neutrons, the atomic mass number would be 23 (11 protons + 12 neutrons).

The mass number of an atom is the sum of protons and neutrons in the nucleus. In this case, the atom has 11 protons and 12 neutrons, so its mass number would be 11 + 12 = 23.
If a sodium atom has 11 protons and 12 neutrons what is its mass number?
The mass number of an atom is the sum of its protons and neutrons. In this case, the mass number of the sodium atom with 11 protons and 12 neutrons would be 23.
An atom of sodium has 11 protons 11 electrons and 12 neutrons What is its atomic number and its mass number?
The atomic number of an atom is the number of protons it has, so in this case, the atom of sodium has an atomic number of 11. The mass number of an atom is the sum of its protons and neutrons, so the mass number of this sodium atom is 23 (11 protons + 12 neutrons).
What is the mass number of an atom with 11 protons 11 electrons 12 neutrons?
Sodium is a metal element. Mass number of it is 23.
How many neutrons have an atom with a mass number of 20 and 11 neutrons?
How many neutrons would it have if it had 11 neutrons? 11.
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.

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.
An atom that has 11 neutrons and an atomic number of 10 has a mass number of what?
The mass number of this atom is (10 + 11 =) 21.Remember:Mass number is the sum of (the number of) neutrons (= 11) and protons.Atomic number is equal to the number of protons (= 10)This atom is the least abundant isotope of neon, 2110Ne (< 0.3%)
What is the mass number of a carbon atom with 5 neutrons?
Carbon's atomic number is 6, therefore it has 6 protons in its atoms. Mass number is the sum of protons and neutrons in the nucleus, which is 6 + 5 = 11.
