the smallest particle in the element
Protons. All atoms of the same element have the same number of protons in their nucleus, which defines their element and gives them their unique properties.
All atoms in the beginning were hydrogen atoms.
A mole of atoms of any element contains the same number of atoms, which is Avogadro's number (6.022 x 10^23). Therefore, a mole of atoms of one element is equivalent in quantity to a mole of atoms of another element. The only difference lies in the atomic weight of the elements.
All atoms of a single element have the same number of protons in their nuclei, which defines the element's atomic number. This characteristic gives each element its unique chemical properties. Additionally, while they may vary in the number of neutrons (resulting in different isotopes), the electron configuration, which determines how atoms interact with each other, is also consistent among atoms of the same element.
2 moles of ANY element contains 2x6.02x10^23 atoms of that element = 1.2x10^24 atoms.
All the atoms have the same number of protons (element type).
All atoms of any single element have the same number of protons and electrons.
An atomic number is actually related to an element and not an atom. Therefore, the question is not relevant. It is NOT atoms that have an atomic number; it is the element.
Protons. All atoms of the same element have the same number of protons in their nucleus, which defines their element and gives them their unique properties.
Dalton's theory was based on five principle: 1.An element is fundamentally different from any other element. 2.All atoms of a each element are identical. 3. Atoms from one element can combine with atoms from another element to form compounds. 4. Atoms cannot be created or divided 5. Element are made of small particle called atoms.
The number of protons is identical in all atoms of an element.
A substance in which all atoms are identical is called an element.
protons
An atom is the smallest unit of any element.
When all atoms in a substance are alike, the substance is an element. Each element is composed of atoms that have the same number of protons in their nucleus.
All atoms in the beginning were hydrogen atoms.
Because they are all the same type of atoms. Oxygen is an element. If you have 10 oxygen atoms, they will all behave like oxygen, since they are the same element.
