What else can I help you with?
What do you have when you subtract the atomic no from atomic mass?
Atomic number is number of protons in an atom while atomic mass is the sum of protons and neutrons in an atom when you subtract you will get the number of neutrons in an atom.
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 number of protons plus the number of neutrons in an atom always a whole number?
The two are counts and so natural numbers. The set of natural numbers is closed under addition.
How do you get atomic mass?
Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom.--> Atomic Mass = protons + neutrons
Why are all atomic numbers whole numbers?
The atomic number is the number of protons.
Atom does not have to have equal numbers of protons and?
neutrons in order to be stable. The number of protons determines the element's identity, while the stability of the nucleus is influenced by the balance of protons and neutrons. Isotopes can have different numbers of neutrons while maintaining the same number of protons.
What subunits are present in equal numbers in an atom?
Protons, neutrons, and electrons are subunits present in equal numbers in an atom. The number of protons in an atom is equal to the number of electrons, while the number of neutrons can vary in different isotopes of an element.
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.
An atom that has more neutrons than protons is called what?
An atom with more neutrons than protons is called an isotope. Isotopes of an element have the same number of protons (same atomic number), but different numbers of neutrons (different atomic mass).
What is an atom's mass number?
An atom's mass number is the total number of protons and neutrons in its nucleus. It is used to identify isotopes of an element since isotopes of the same element have the same number of protons but different numbers of neutrons.
Why atomic mass is different from the mass numbers?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
What mass number is calculated by adding the numbers?
the mass number of an atom is the number of protons in an atom, plus the number of neutrons.
What is the sum of protons and neutrons in an atom?
Mass number!:)
An isotope is identified by its atomic mass number which is the total number of?
protons and neutrons in the nucleus of an atom. Isotopes of an element have the same number of protons but different numbers of neutrons. The number of neutrons in an atom affects its stability and often determines its nuclear properties.
An atom with 55 protons and 76 neutrons?
An atom with 55 protons is a cesium atom. The mass number is the sum of the numbers of protons and neutrons, in this instance 131. Therefore, the atom is Cs-131.
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?
The atom has 84 protons (atomic number) and 126 neutrons (mass number - atomic number).
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.
