How can two atoms of the same element have different numbers 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.

Why can two different elements have the same atomic number?

No, because each element has its own specific property, BUT certain elements have similar properties, like elements in the same family. The atomic number is associated to the element’s composition for one atom, in which the atomic number = number of protons in the atom with a neutral charge.

What is an element that has the same number of protons but different numbers of neutrons?

Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table.

Can an element have atoms with different numbers 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.

How do you know if two atoms are the same element?

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”.

Which two atoms have the same mass?

Atoms of an element with the same mass number make up an isotope of the element. Different isotopes of the same element cannot have the same mass number, but isotopes of different elements often do have the same mass number, e.g., carbon-14 (6 protons and 8 neutrons) and nitrogen-14 (7 protons and 7 neutrons).

Can 2 different elements have the same mass number?

Different isotopes of the same element cannot have the same mass number, but isotopes of different elements often do have the same mass number, e.g., carbon-14 (6 protons and 8 neutrons) and nitrogen-14 (7 protons and 7 neutrons). …

Which property is unique for each element?

Each element has its own unique properties. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. The atomic number of an element is equal to the number of protons that element contains.

Is the number of protons always equal to the number of neutrons?

The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Which two has the same mass number?

Do all atoms have neutrons?

All elements have atoms with neutrons except for one. A normal hydrogen (H) atom does not have any neutrons in its tiny nucleus. That tiny little atom (the tiniest of all) has only one electron and one proton. Deuterium is a hydrogen atom with an extra neutron and tritium has two extra.

Can elements have more than one atom?

An elements is a substance which is made out of atoms that all have the same proton number. So an element can consist of multiple atoms (like oxygen which goes around in pairs). An atom consists of a nucleus and some electrons.

Can a atom of the same element have different number of neutrons?

Atoms of the same element can have a different number of neutrons. These atoms are called isotopes, which are atoms of the same element that have a different number of neutrons. Subsequently, question is, can isotopes have different number of electrons?

Do you always have equal number of electrons and protons?

Atoms do not always contain the same number of electrons and protons, although this state is common. When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons).

Is it true that all things are made of atoms?

Yes, all things are made of atoms, and all atoms are made of the same three basic particles – protons, neutrons, and electrons. But, all atoms are not the same. You know that the number of protons in an atom determines what element you have. For instance hydrogen has one proton, carbon has six.
