The sum of the protons and neutrons in an atom equals the .?
atomic number
What is the mass number of a zinc atom that has 37 neutrons?
The mass number of an atom is the sum of its protons and neutrons. For a zinc atom with 37 neutrons, the mass number would be the number of protons (30 for zinc) plus the number of neutrons (37), which equals 67.
How many protons and neutrons are there in the nucleus of an atom that has an atomic number of 84 and a mass number of 210?
84 protons, the same as the atomic number, and (210 - 84) or 126 neutrons. The numbers of protons and neutrons together equals the mass number.
What is the sum of protons and neutrons in an atom?
Mass number!:)
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
The mass of an atom is eaual to?
The mass of an atom equals to the number of protons and neutrons.
What is the sum of the protons and neutrons in an atom equals to?
The nucleon number (or mass number).
The sum of the protons and neutrons in an atom equals the .?
atomic number
An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
Atomic mass equals the number of what?
The atomic mass NUMBER equals the number of protons and neutrons in an atom. DO NOT confuse this with the mass of an atom.
What is the mass number of a zinc atom that has 37 neutrons?
The mass number of an atom is the sum of its protons and neutrons. For a zinc atom with 37 neutrons, the mass number would be the number of protons (30 for zinc) plus the number of neutrons (37), which equals 67.
What is the Mass number of helium atom that has two protons and two neutrons?
4 because the mass number equals protons plus neutrons. Which is 4.
When is an atom neutral When mass number equals number of protons equals number of electrons or when atomic number equals number of protons equals number of electrons?
An atom is neutral when the number of protons in the nucleus equals the number of electrons surrounding the nucleus. This means that the atom has no overall charge, as the positive charge of the protons is balanced by the negative charge of the electrons. The mass number, which is the sum of protons and neutrons, does not necessarily impact the neutrality of the atom.
How many protons and neutrons are there in the nucleus of an atom that has an atomic number of 84 and a mass number of 210?
84 protons, the same as the atomic number, and (210 - 84) or 126 neutrons. The numbers of protons and neutrons together equals the mass number.
What is the sum of protons and neutrons in an atom?
Mass number!:)
In an atom the number of proton equals the number of neutrons?
In an atom, the number of protons is equal to the number of electrons in order to maintain electrical neutrality. However, the number of neutrons in an atom can vary, leading to different isotopes of the element.
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.
