What is the same for atoms of the same elements?

Atoms of the same element have the same atomic number so the number of protons (and electrons) are same. But they have same or different mass numbers (like that for isotopes). Different mass number will have different number of neutrons.

What are particles of the same element?

each element is made up of identical particles of matter called atoms. all the atoms in a pure substance or element are identical to one another but different to the atoms in a different element.

Which nuclear particle is always the same for atoms of the same element?

The number of protons is always the same in atoms of the same element. The number of neutrons can be different, even in atoms of the same element. Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes.

What is an atom 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.

Which particles will always have the same number in an atom?

Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well.

Why are atoms of elements the same?

Elements and Atomic Number What makes something an element is the fact that all the atoms have the same number of protons in the nucleus.

What is it called when all particles are the same?

All the substances which are made up of the same kind of particles are called pure substances.

What do all atoms of the same element have in common?

Atoms of the same element always have the same number of protons, same Z, but often have different numbers of neutrons, therefore, different mass numbers.

Are protons and electrons equal?

The number of electrons on a neutral atom is equal to the number of protons in the nucleus of the atom.

Are protons and neutrons equal?

For most of the 16 lightest elements (up to oxygen) the number of neutrons is equal to the number of protons….2.1 Electrons, Protons, Neutrons, and Atoms.

Elementary Particle	Charge	Mass
Proton	+1	1
Neutron	0	1
Electron	−1	~0

Are protons and electrons same?

Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force.

Are protons and electrons the same?

Are protons and electrons the same number?

The number of electrons in a neutral atom is equal to the number of protons.

What makes two elements the same?

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. … All isotopes of a particular element have the same number of protons but can have different numbers of neutrons.

Are all particles the same?

We consider the possibility that all particles in the world are fundamentally identical, i.e., belong to the same species. Different masses, charges, spins, flavors, or colors then merely correspond to different quantum states of the same particle, just as spin-up and spin-down do.

Are electrons identical?

Every electron in the universe has exactly the same mass, exactly the same charge, and if you think about it, there's no reason why they'd have to be. In 1940, physicist John Wheeler came up with a novel new theory that might explain why all electrons are identical.

What elements have the same atomic number?

Atoms of the same element having the same atomic number but different mass are called isotopes. They have same number of protons and electrons but different number of neutrons. For example: Hydrogen – protium (11H), deuterium (12H) and tritium (13H) are isotopes.

What do all atoms of the same element have in common quizlet?

Atoms of the same element all have the same number of protons but they can have different numbers of neutrons. This is why different atoms of the same element can have different atomic masses.

Are protons and neutrons the same?

Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral).

Is proton and electron the same?

Do atoms have same number of protons and neutrons?

Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom.

Are all subatomic particles identical?

The truth is, all subatomic particles of a particular kind are identical with each other. That is, all electrons are the same as each other, all protons are the same as each other, all neutrons are the same. It doesn't even stop there.

Are protons and electrons identical?

The truth is, all subatomic particles of a particular kind are identical with each other. That is, all electrons are the same as each other, all protons are the same as each other, all neutrons are the same.

Is every proton the same?

Protons and neutrons are made of smaller “particles” called quarks. However, all protons are identical to each other, regardless of which element they are a part of. So, every proton is made of the same combination of 3 quarks.

What do all atoms of the same elements have in common?

Atoms of the same element always have the same number of protons, same Z, but often have different numbers of neutrons, therefore, different mass numbers. These atoms are called isotopes and are introduced in next section. The most common carbon atoms have six protons and six neutrons in their nuclei.

Do atoms of the same element have the same number of protons?

Atoms of the same chemical element do not always have the same mass because, although the number of protons in the nucleus is the same for all atoms of the same element, the number of neutrons is not. Most elements as they occur naturally on earth are mixtures of several isotopes.

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

All atoms of a chemical element have the same atomic number (number of protons in the nucleus) but may have different mass numbers (from having different numbers of neutrons in the nucleus).

What do atoms have the same number of?

Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom.

Are all particles same?

Are all protons and neutrons the same?

Neutrons are all identical to each other, just as protons are. Atoms of a particular element must have the same number of protons but can have different numbers of neutrons.
