A substance in which all atoms are identical is called an element.
A substance in which all atoms are alike is an element.
A substance whose atoms are all the same kind is an element, which is a pure substance.

The smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms is a molecule.
Because the differences in atoms make different elements. Elements are multiple of similar atoms.
no of atoms = weight of the given substance/ atomic mass of substance according to the question:- no of atoms = 3/32 answer
They all keep time: Cesium atoms, quartz crystals, and pendulums all vibrate at a constant frequency (not the same frequency for each substance.) With current technology, cesium atoms are the most precisely constant.
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
A substance in which all atoms are alike is an element.

nucleus compound
True statements: All neutrons are alike, all electrons are alike, all protons are alike (All atoms of a given isotope is only alike). False statement: All atoms are alike All atoms are not alike as they may vary in the number of protons / electrons / neutrons.
neutrons of all atoms are alike
