the Atomic Mass of carbon 13 is 13 lt has six protons how many neutrons does this isotope
What else can I help you with?
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
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.
The mass number is used to calculate the number of?
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
The mass number is used to calculate the number of what?
The number of protons and neutrons in the nucleus
If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
If the atomic mass of the atom is 48 and it contains 20 protons, then the atom contains 28 neutrons. This can be calculated by subtracting the number of protons from the atomic mass, since the atomic mass includes both protons and neutrons.
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
What is the sum of protons and neutrons in an atom?
Mass number!:)
If the atomic mass of an atom is 38 and the atom contains 15 protons how many neutrons does the atom contain?
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
Which subatomic particles of an atom are responsible for atomic mass?
Protons and neutrons are responsible for the atomic mass of an atom. Protons have a positive charge, while neutrons have no charge. The combined mass of protons and neutrons makes up the majority of the mass of an atom.
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
How many protons and neutrons does a carbon atom with a mass number of 12 have?
A carbon atom with a mass number of 12 has 6 protons (which is the atomic number of carbon) and 6 neutrons.
How many protons and neutrons are in the atom oxygen?
An oxygen atom has 8 protons and usually 8 neutrons, resulting in an atomic mass of 16.
What particles make up the mass of an atom?
The number of protons
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
An atom has 13 protons and an atomic mass of 27 How many neutrons does this atom have?
The atom in question has 13 protons, so is atomic number 13, which is Aluminium. Assuming that all of the atom's mass is formed from the protons and neutrons, and each of these have atomic mass 1, the number of neutrons is 27 - 13 = 14 neutrons. Almost all Aluminium is of this isotope.
