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?
11
An element has a atomic number of 11 and an atomic weight of 23 how many neutrons does each atom contain?
The answer cannot be determined with atomic weight. You are asking for the number of neutrons in a particular isotope of sodium. You need mass number for the isotope you are interested in, which is probably 23.Assuming you mean atomic number of 11 and a mass numberof 23, there would be 12 neutrons in each atom of this isotope.
If an atom has 11 protons 12 neutrons and 11 electrons what is the identify of the element and it's mass number?
It is a radioactive scandium isotope - 43Sc with 21 electrons and protons, and 22 neutrons.
If an atom has 8 protons and 11 neutrons and 8 electrons what is the atomic mass of the atom?
The atomic mass of an atom with 10 Electrons and 11 Protons would be 11, assuming that there are no Neutrons present in the nucleus. If there are Neutrons present, they would add 1 for 1 to the mass.
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.
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 mass of an atom with 11 protons 12 neutrons 11 electrons?
23 is the mass number, the mass number consists of protons and neutrons together, 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 a mass number of an atom that has 12 netrons and 11 protones?
An atom of atomic number 12and mass number 22 contains how many protons?
How does an atom of sodium has a larger mass than a atom of neon. how is this possible when neon has so many more valence electrons?
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.
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.
If a sodium atom has 11 protons and 12 neutrons what is its mass number?
23
What atom has six neutrons and a mass number of 10 amu?
Boron: Mass is 10.811 11 - 5 (Z or element number) = 6 neutrons.
An atom of sodium has 11 protons 11 electrons and 12 neutrons What is its atomic number and its mass number?
23
How many neutrons and protons does neutral atom of sodium with an atomic mass number of 23 have?
Every sodium atom has 11 protons, the atomic number of sodium. The isotope with mass number 23 has (23 - 11) or 12 neutrons, because the mass number of an isotope is defined as the sum of the numbers of protons and neutrons in the isotope.
Boron has an atomic mass of 11 and an atomic number of 5 how many neutrons must there be?
The mass of an atom is found by adding the number of the protons and neutrons. So, a boron atom with 5 protons and 6 neutrons would have an atomic mass of 11.
