Isotopes are atoms with a different number of neutrons than protons and electrons. The word isotope comes from the Greek words "isos" meaning equal and "topos" meaning place. Isotope means "same place".

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.


What is a direct consequence of the number of protons and neutrons in an atom's nuceuls?

Number of proton = atom numberfor example:Hydrogen has 1 proton and its atom number is also 1Number of neutrons + number of protons = mass numberfor example:Hydrogen have 1 proton and and NO neutrons, so the mass number is 1Helium has 2 protons and and 2 neutrons, so the mass number is 4


What is the number of protons and neutrons called?

The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.


Why can an atom have the same number of neutrons and still be an isotope?

an isotope is defined by an atom with the same number of protons, but a different number of neutrons


What does the Mass number in chemistry represent?

The mass number in chemistry represents the total number of protons and neutrons in an atom's nucleus. It is used to identify isotopes of an element, where different isotopes have the same number of protons but a different number of neutrons.
