Do all elements contain the same types of subatomic particles?

An atom is the smallest unit of matter that retains all of the chemical properties of an element. The attraction between the positively charged protons and negatively charged electrons holds the atom together. Most atoms contain all three of these types of subatomic particles—protons, electrons, and neutrons.

Does an atom have to have the same number of each particle?

Atomic particles Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well.

Do all atoms of the same element have the same number of neutrons?

All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. For example, all carbon atoms have six protons, and most have six neutrons as well. Atoms of the same element that differ in their numbers of neutrons are called isotopes. Many isotopes occur naturally.

What subatomic particles do not have charge?

There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge. Neutrons, on the other hand, don’t have a charge.

What is true for all atoms of the same element?

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.

Which subatomic particle is not the same for different elements on the periodic table?

Unlike protons, the number of neutrons is not absolutely fixed for most elements. Atoms that have the same number of protons, and hence the same atomic number, but different numbers of neutrons are called isotopes.

Which particles have the same number in all the atom?

The two particles in the atom that are equal in number are the protons and electrons. The protons are located in the nucleus along with neutrons.

Are all atoms the same?

Everything in this world are matter and comprises of atoms. But each and every atom is unique. They are not the same at all. Every atom consists of three basic units protons, neutrons, and electrons and these units determine the physical and chemical properties of an atom and matter.

Are all atoms the same element?

No. Although two such atoms are essentially chemically identical (they will chemically react in the same way), they are not completely identical. 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.

Which statement about subatomic particles is not true?

The statement that is not true about subatomic particle is that all electrons and atom contain the same amount of energy.

What subatomic particles determine the charge of an atom?

Atoms contain negatively charged electrons and positively charged protons; the number of each determines the atom’s net charge.
