Number of protons
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).
The nuclei of all atoms of a given element always have the same number of protons. This number is unique to each element and is known as the element's atomic number.
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.
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
It is the same. 1 mole is always 23 6.022x10 from wikipedia under "Mole (unit)", "one mole of iron contains the same number of atoms as one mole of gold;" It is the same. 1 mole is always 6.022 x (10 to the 23rd) from wikipedia under "Mole (unit)", "one mole of iron contains the same number of atoms as one mole of gold;"
Yes
Yes, all atoms of argon have the same atomic number, which is 18. Atomic number refers to the number of protons in the nucleus of an atom, and for argon, it always remains constant at 18.
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).
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.
The nuclei of all atoms of a given element always have the same number of protons. This number is unique to each element and is known as the element's atomic number.
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.
