The atomic number is how many protons there are, and since the number of protons is equal to the number of electrons, it is also the number of electrons. You can take the number of protons away from the atomic weight (overall weight) which will give you the number of neutrons. (Electrons don't weigh anything in the atomic weight so you don't need to subtract this as well). Hope this helps :D
The number of protons/electrons in an atom of that element.
If an atom were to change the number of protons it had than it would change the atomic number and therefore become a different element. Radioactive decay is one example of this, for example, alpha decay is when a radioactive nucleus emits an alpha particle (2 protons + 2 neutrons) and in doing so, becomes a nucleus of a different element. Polonium-212 decays to Lead-208 in this way.
Different atoms either have a different number of protons(which makes them different elements) or a different number of neutrons (which makes them isotopes of the same element).For example, hydrogen has one proton (and usually no neutrons) while helium has two protons (and usually two neutrons). However, hydrogen with one proton and two neutrons is called tritium(3H) while helium with two protons and one neutron is called helium-3 (3He).
that is my question but people give the wrong answers like me. xD
false
The Periodic Table is organized by atomic number, metals, nonmetals, metalloids, periods, groups, and stability.
The number of protons an element has.
the atomic number <<< apex : )
Number of protons = the atomic number of the element
You can find the Atomic Number, Atomic Mass, The Element symbol and Name and sometimes, the numbers of the electrons in each shell. (for a Bohr model)Also element symbol can be called atomic symbol.The information is the atomic number, also stands for how many electrons and protons there are in that element, also it tells what the atomic abbreviation is and the real name.Each square on the periodic table gives information about an element. On many printed periodic tables we can have atomic number, atomic weight and some other properties like melting and boiling points may also be included.the atomic number and the atomic mass. the atomic number tells you how many neutrons and electrons are in the atom, and the atomic mass tells you the combined amount of protons and neutrons and that element. there is also the symbol of the element, which is the symbol for it's name, and most tables provide the name of the elements.Most basic periodic tables contain four pieces of information for each element: the element's name, symbol, atomic number, and atomic mass. For example, the first element would have an "H", the name Hydrogen, a number 1, and a number 1.0079. H is hydrogen's symbol. The 1 is hydrogen's atomic number, which is the number of protons its nucleus. The 1.0079 is hydrogen's atomic mass.More detailed periodic tables may include number of valence electrons, electron configuration, electronegativity, ionization energy, and other properties.It varies depending on which table you use. A general table will give you the atomic number, element symbol, and atomic mass.The periodic table contains several pieces of information about each element. The element's square on the table includes its atomic symbol, atomic number, and atomic weight.Each square represents the name of the element, the atomic number, and the atomic mass of the element.

Platinum is a non metal element. Atomic number of it is 78.
The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
Atomic mass is the average mass of all isotopes of a given element.
28/14 Si Its the number they give you which is the atomic mass of the isotope over the atomic number and the symbol of the element.
equal to number of protons
Atomic mass minus atomic number will give you the average number of neutrons in that element. Bear in mind that atomic mass is based on the actual weight of that element, which is the result of whatever isotopes appear in nature; it is rarely based on only a single isotope.
Atomic no. helps to know 1. the position of element in the periodic table2. Common properties3. Electronic Configuration4. Common electrovalencies and oxidation states.5. Many other properties.
