What is it called when two atoms of the same element have a different number of neutrons?

What is it called when two atoms of the same element have a different number of neutrons?

For example, all carbon atoms have six protons, and most have six neutrons as well. But some carbon atoms have seven or eight neutrons instead of the usual six. Atoms of the same element that differ in their numbers of neutrons are called isotopes. Many isotopes occur naturally.

What is it called when there are two atoms of the same element with different atomic masses?

Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.

What are atoms with different numbers called?

Two atoms with the same atomic number, but different mass numbers (same number of protons, different number of neutrons), are called isotopes, or isotopic nuclides. Having different numbers of neutrons changes the mass of these atoms, so isotopes have slight variations in their physical and chemical behavior.

When two atoms of the same element have a different number of?

isotopes
The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element. We refer to the atoms of the same element with different numbers of neutrons as “isotopes”.

When two atoms have the same atomic number they have the same number of?

More specifically, atoms that have the same number of protons in their nucleus belong to the same chemical element. The number of protons an atom has in its nucleus is given by the atomic number. An atom’s mass number tells you the number of protons and neutrons that atom has in its nucleus.

Can two atoms of the same element have different atomic numbers?

The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element. We refer to the atoms of the same element with different numbers of neutrons as “isotopes”.

Can two elements have the same number of electrons?

In any neutral atom, the number of electrons is the same as the number of protons. As a result, isotopes of the same element also have the same number of electrons and the same electronic structure.

How do you find two atoms of the same element?

Hint: All atoms of a given element are identical in mass and properties. Atoms of the same element consist of the same atomic number that is number of protons or electrons and different mass number that is number of neutrons.

What makes atoms of different elements different?

The number of protons in an atom is the defining feature of an atom. It’s what makes one element different from another. The number of protons in an atom is called its atomic number. All the elements in the universe are arranged according to their atomic number in the periodic table.

What are two atoms with the same atomic number but different atomic mass called quizlet?

Atoms with the same atomic number and different atomic masses are referred to as isotopes.

What refers to atoms of the same element with the same number of protons but different number of neutrons?

Isotopes. An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.

Can two different elements have the same atomic number quizlet?

Two different elements can have the same atomic number. The sum of the protons and neutrons in the nucleus of that atom. Atoms of the same element that have different mass numbers.
