Can 2 substances on the periodic table have the same atomic number?
no
If you have 2 atoms have the same number of protons but differernt number what will they have the same?
They will have the same atomic number.
What 2 subatomic particles can you determine from the atomic number?
Atomic number is same as the number of protons and number of electrons.
What is the atomic number of He plus?
The atomic number of helium (He) is 2. When He gains one electron to become He plus, it becomes an ion with a net charge of +1, but the atomic number remains the same as 2.
What is meant by element?
Elements are pure substances inwhich all the atoms have the same number of protons (same atomic number) and thus have the same chemical properties. They cannot be separated by normal chemical means into any simpler substances.
What are 2 atoms with the same atomic number but different atomic weight?
ion
What is the atomic number of S-2?
The atomic number of sulfur is 16 The number of protons is the same as the atomic number. The S-2 gains 2 electrons so it changes from 16 to 18. The atomic mass is 32. The atomic mass number minus the number of protons will give you 16 which is the number of neutrons. :)
Are atoms with the same atomic number atoms of the same element?
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
What is a substance that cannot be separated or broken down into simpler substance by chemical means all atoms of an element have the same atomic number?
1. You think probable to the atoms of chemical elements. 2. Al l atoms of the same chemical element have the same atomic number.
If 2 atoms have the same number of protons but different number of neutrons will they have the same atomic number?
Yes. The only difference is the atomic mass. They are the same element, therefore the same Atomic Number (represented as 'Z') The reason for the different amount of nuetrons is because of isotopes or radiation of that specific element.
Do alpha prarticle share the same atomic number?
An alpha particle is, essentially, a helium nucleus.This means that is has the same atomic number (no. of protons) as Helium does - it just doesn't have the electrons as well.So the atomic number of an alpha particle would be 2.It's also not neutral, and would have a 2+ charge.The mass number of an alpha particle would be 4 as it has 2 neutrons and 2 protons.All alpha particles are helium nuclei, so they all share the same properties.
What is the atomic number for helium?
The atomic number of Helium is 2.
