What else can I help you with?
Atoms have a mass number equal to the sum of?
the protons and neutrons.
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.
How can an atoms mass number be determined?
it is the sum of the protons and neutrons present in the nucleus of the atom.
Are there the same number of portons and neutrons in an atom?
No, atoms do not always have the same number of protons and neutrons. The number of protons determines the element, while the sum of protons and neutrons determines the isotope of an element. Some atoms have equal numbers of protons and neutrons, but others have different numbers.
What makes an atoms mass number?
An atom's mass number is determined by the sum of its protons and neutrons. Protons have a positive charge and determine the element's identity, while neutrons help stabilize the nucleus and contribute to the atom's mass.

The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What determines an atoms atomic mass?
It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Are there the same number of portons and neutrons in an atom?
No, atoms do not always have the same number of protons and neutrons. The number of protons determines the element, while the sum of protons and neutrons determines the isotope of an element. Some atoms have equal numbers of protons and neutrons, but others have different numbers.
What is the sum of protons neutrons in an atom?
Mass number = Protons+Neutrons
What makes an atoms mass number?
An atom's mass number is determined by the sum of its protons and neutrons. Protons have a positive charge and determine the element's identity, while neutrons help stabilize the nucleus and contribute to the atom's mass.
What Make up nearly all of an atoms mass?
The sum of all protons and neutrons - Apex Learning
Which trem describes the sum of the number of protons and neutrons in an atom?
"Atomic mass" is the sum of the number of protons and neutrons in the nucleus of the atom. All atoms of an element have the same number of protons. For example, all iron atoms have 26 protons. But while most (90%) have 30 neutrons, there are isotopes of iron that have anywhere from 26 to 36 neutrons. So the published "atomic mass" is the weighted average of the combined number of protons and neutrons. That's why the atomic number is always a whole number, but the atomic mass is a decimal.
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.
How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an atom is the sum of its protons and neutrons. It represents the total number of nuclear particles (protons and neutrons) in the atom's nucleus. The number of protons in an atom determines its element, while the number of neutrons can vary to create different isotopes of the element.
