Molecules is actually an incorrect answer, as molecules are assortments of atoms that are bonded together via their electron(s) either by covalent or ionic bonds. An atomic number is a number that signifies an atoms number of protons. All elements are atoms, and there are 118 known elements, all with different atomic numbers, for they each have different amounts of protons. In essence, the atomic number DEFINES the atom, for instance Hydrogen (H+), has only one proton, while Ununotium has 118 protons. So if an atom has a different number of protons in its nucleus than another atom, then they always will be different elements. Therefore they are not "grouped" into anything other that most basically the Periodic Table.
So to answer your question directly, there is no "group" to speak of, for all atoms with the same atomic number are essentially the same type of atom.
You may have meant neutrons, as atoms that are the same but with varying numbers of neutrons can still be the same element, yet differ in neutrons in the nucleus. These are called Isotopes.
No. Each type of atom (element) has its own unique number of protons, which is called the atomic number. Atoms of the same element will always have the same atomic number (number of protons). Atoms of different elements will never have the same atomic number (number of protons).
Atoms with the same number of protons but different mass numbers are called isotopes. Isotopes have the same atomic number but different atomic weights due to variations in the number of neutrons in the nucleus.
All atoms have atomic numbers which are the same and the atoms have the same number of electrons.
Number of protons
A mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23 atoms. So, a mole of calcium (atomic number 20) will contain twice the number of atoms as a mole of neon (atomic number 10), as the atomic number corresponds to the number of protons in an atom.
isotopes Atoms of the same element are called Isotopes. they have the same number of atoms (i.e. same atomic number) but different number of neutrons
Atoms of the same Element have this.
yes. Isotopes of an element have the same number of protons, thus electorns, thus the same chemical properties. Where isotpes differ is in the number of neutrons. Consider hydrogen, atomic number 1, atomic weight 1, 1 proton, 1 electron vs duterium, atomic number 1 atomic weight 2, 1 proton, 1 electron, 1 neutron. H2O = water D2O = heavy water
Yes, all carbon atoms have the same atomic number, and that is 6.
Atoms with the same atomic number are all atoms of the same element. However, if the atoms have different molecular weights, they are isotopes of the same element.
All atoms with the same number of protons are atoms of the same element. The number of protons is the atomic number of the element.
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
Atoms atomic number represents their number of protons.
If two atoms have the same atomic number, it means they have the same number of protons in their nucleus. If they also have the same atomic mass, it means they have an equal number of protons and neutrons. These atoms would be isotopes of the same element.
Yes
They will have the same atomic number.
A pure substance in which all the atoms have the same atomic number or number of protons is an element.
