Best Answer

An atom must gain or lose protons from its nucleus to become an atom of another element.

The number of protons, and to a much lesser extent the number of neutrons, will determine the chemical properties of an element.

The number of protons in the nucleus must change for an atom to become a new element. This changes the atomic number, which defines the element. Changing the number of electrons or neutrons does not change the element.

If the number of protons in an atom changes a new element is formed?

Yes, changing the number of protons in an atom results in a different element because the number of protons determines the element's identity on the periodic table. This change alters the atomic number, which defines the element's chemical properties.


Why must the number of protons always stay the same in an atom?

The number of protons in an atom determines its identity as a specific element. Changing the number of protons would result in a different element. Therefore, the number of protons must remain constant in order to maintain the stability and characteristics of the atom.


Is 1 atom of carbon a molecule or element?

One carbon atom is an element. You must have two or more atoms to make a molecule.


An atom of any element must contain?

An atom of any element must contain protons, neutrons, and electrons. The number of protons in the nucleus determines the element's identity, while the neutrons and electrons help determine its stability and reactivity.


Is a atom an element?

No, an atom is not an element. An atom is the smallest unit of an element that retains the properties of that element. Elements are made up of atoms of the same type.


Is insulin an element?

No, insulin is not an element. To be an element, a substance must have all the same type of atom. Once it has this, it can go on the Periodic Table. So, as insulin has many different types of atom in it, it's not an element.

What part of the atom has to stay the same for it to be the same element?

The number of protons in the nucleus must stay the same for an atom to be the same element. This is because the number of protons determines the element's identity on the periodic table.
