What are atoms that have the same number of protons but different numbers of neutrons quizlet?
Isotopes are atoms of the same element that have the same number of protons but a different number of neutrons. Therefore, isotopes have the same atomic number (number of protons) but a different mass number (number of protons plus number of neutrons).
What are all atoms with the same number of protons called?
Isotopes are atoms of the same element (same number of protons) that have different numbers of neutrons in their atomic nuclei.
What are the atoms containing same number of neutrons?
Hint: Atoms having the same number of neutrons are called isotones. The mass number (A) is the sum of the number of protons (Z), and the number of neutrons (N). The number of nucleons is the sum of neutrons and the number of electrons or protons.
What has the same number of protons?
All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms. For example, all helium atoms have two protons, and no other elements have atoms with two protons….Atomic Number.

Which atom that contains the same number?
Isotopes are atoms of the same element that contain an identical number of protons, but a different number of neutrons.
Do atoms of the same element have the same atomic number?
All atoms of an element have the same atomic number. All isotopes of the same element, such as hydrogen, have the same number of protons (same atomic number) but different numbers of neutrons in their nuclei. There are three isotopes of hydrogen; hydrogen-1, hydrogen-2, and hydrogen-3.
Do all atoms have the same atomic number?
Although all atoms of a given element must have the same atomic number, they need not all have the same mass number. These different kinds of the same element are called isotopes. Isotopes are atoms that have the same atomic number (and are therefore of the same element) but different mass numbers.
What are atoms called that have the same number of protons?
What are atoms called that have the same number of protons but different number of neutrons? Isotopes have the same number of protons but a different number of neutrons. Different isotopes of a single element are on the same position on the Periodic Table of elements.
How are protons and neutrons alike and different?
Protons and neutrons both weigh about one atomic mass unit or amu. Isotopes of the same element will have the same atomic number but different mass numbers. Atomic number, chemical symbol, and mass number: Carbon has an atomic number of six, and two stable isotopes with mass numbers of twelve and thirteen, respectively.
Is the atomic number of an element the same?
The atomic number defines the identity of the element: Z = 6, C; Z = 27, Co; Z = 47, Ag. Of course while there may be the same number of nuclear protons, the nucleus may contain different numbers of neutrons; these give rise to different isotopes; same element, and same chemistry, but different atomic mass.
Why are atoms of the same element have different masses?
Atoms of the same element have the same number of protons, but different isotopes have different numbers of neutrons. Different isotopes of the same element have different masses because they have a different number of neutrons. Does an atom has no mass?
