All isotopes of the same element have the same atomic number, so their proton numbers are equal.
They are on the same (= 'iso') place or spot (= 'topos') in the Periodic Table, this is called: iso-topic .
No. Atoms are what make up elements, so they don't count.
He said that atoms were indivisible, and we now know is not true because atoms are composed of protons, electrons, and neutrons, and that protons and neutrons are themselves composed of smaller particles. He also said that all of the atoms of the same element have the same mass, which we now know is not true because of the existence of isotopes.
Either one. This is incorrect. The correct answer would be that it is made of separate atoms because iron is an element or a pure substance. So, therefore it didn't combine with anyother atoms to form a molecule and that being said it is strictly made up of separate atoms and not molecules. Definitely not either one.
A chemical equation is said to be balanced when the number of atoms for each element is the same on both the reactant and product sides of the equation. This means that the law of conservation of mass is obeyed, as no atoms are created or destroyed during a chemical reaction.
Mercury is an element (Hg) so only mercury atoms appear. That being said, natural mercury is likely comprised of several different flavors of the mercury atom, called isotopes, which accounts for why mercury's mass on the periodic table is not a whole number.
An atom is the smallest unit of any element.
An atom is the smallest piece of an element. Said another way, and element is made up one and only one kind of atoms.
Someone Rutherford.
John Dalton
If the atoms of the same element (not only carbon!) occur in different arrangements, they are said to be different allotropes.
The atom is said to be ionized. (It can also be said to be oxidised.)
Atoms with nuclei that are not stable and lose parts through decay are said to be radioactive. This process results in the transformation of the atom into another element, along with the release of energy in the form of radiation.
1 mol of Ag and 1 mol of Au can be said to contain the same amount of atoms of each element.
The statement that atoms of the same element are exactly alike is attributed to John Dalton, who proposed the atomic theory in the early 19th century. Dalton's theory posited that all atoms of a given element are identical in mass and properties, which laid the foundation for modern chemistry. However, it is important to note that later discoveries, such as isotopes, revealed that atoms of the same element can differ in mass due to variations in the number of neutrons.
Neutral atoms of the same element can differ in the number of neutrons, which results in different isotopes of the same element. Isotopes have the same number of protons and electrons, but different numbers of neutrons.
The number of neutrons in the atoms of a specific element can vary, leading to the formation of isotopes. While all atoms of a given element have the same number of protons (defining the element), the neutron count can differ, affecting the atomic mass and stability of the isotopes. For example, carbon typically has six neutrons, but carbon-14, an isotope of carbon, has eight neutrons. These variations can influence the element's properties and behavior in chemical reactions.
Atoms of a given element have a specific number of electrons that equals the number of protons in their nucleus, which defines the element's atomic number. For example, carbon has six protons and six electrons. In neutral atoms, the number of electrons matches the number of protons, but ions can have more or fewer electrons due to gaining or losing them. Thus, the number of electrons in an atom of a specific element can vary in ionic forms but remains constant for neutral atoms.
