A Periodic Table is your best bet.
periodic tables can range in complexity but most will tell you the atomic number (located left upper corner) and the average Atomic Mass (right upper corner). with these two numbers you can work out protons and neutrons by realizing that the atomic numbers is = to # of proton and that because the proton and neutrons are ~1 amu in mass with electron have negliable mass
Average atomic mass - atomic number = # of neutrons
you will realize that this # is often not a whole number. that is because the same element (elements with same atomic number) may have different numbers of neutrons and the average atomic these are called isotopes. most elements will have a main isotope and some minor isotopes that makeup a same percentage of the total.
this is why you often see average mass of xx.99 like Cr which is 51.996 meaning that most of the isotopes will have a atomic mass of 52 (24 protons and 28 neutrons) and a relatively small percentage will have a mass of 51 (again 24 protons because it is still Cr but now 27 neutrons)
As for the number of electrons, this depends on what kind of chemistry the element is involved with. Just keep in mind that a neutrally charged molecule has the same number of + charges (protons) as - charges (electrons)
it however has 15 protons , 15 electrons , and 16 nuetrons
protons= 74 neutrons= 110 electrons= 74
Xenon has 54 protons, 77 neutrons, and 54 electrons. The number of protons determines the element's chemical properties, while the total number of protons and neutrons determines the atomic mass. Electrons equal the number of protons in a neutral atom.
Argon has 18 electrons and protons...Neutrons is 22
To determine the number of electrons in an element, you can look at the atomic number of the element on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
26 nuetrons, 22 electrons, and 22 protons
Sc is a 3d element. It has 21 protons and 21 electrons.
5 protons 8 neutrons try it
no it has a nutral charge because in the middle of protons and electrons there is nuetrons. nuetrons have a nutral charge and so does the atom.
The chemical element of chlorine has 18 nuetrons,17 protons and 17 electrons
An element has a small case in the center called the nucleus. Inside the nucleus contains protons an nuetrons. Protons have a positive charge and nuetrons have a negative charge. On the outside and are energy levels that have electrons and are negatively charged
protons and nuetrons are equal to no. of electrons present in atom
Electrons, protons, and nuetrons. electrons are outside the nucleus, and protons and nuetrons are inside the nucleus.
it however has 15 protons , 15 electrons , and 16 nuetrons
The number of protons determine the atomic number of an element. There are the same amount of protons as electrons in a regular element.
protons= 74 neutrons= 110 electrons= 74
The number of protons determine the atomic number of an element. There are the same amount of protons as electrons in a regular element.
