Number of protons located in the nucleus.
Atomic number = number of protons as well as the number of electrons in an atom.
The atomic number of an atom is the atoms number of protons. The number of protons is same as the number of electrons.
The atomic number of each element is on the periodic table. The elements are arranged on the periodic table in order of increasing atomic number.
ATOMIC NUMBER YEAR IN WHICH IT WAS DISCOVERED? it was discovered in 1913 by British physicist Henry Mosely
mass number and atomic number of an atom
Atomic number tells you the number of protons. There is no need to define a standard state.
atomic weight
no i cant answer it
The atomic number increases from left to right across a period (row). This is because the atomic number is the number of protons in the nuclei of the atoms of each element. No two elements have the same atomic number. It is the protons that define an element.
The atomic number represents the number of protons in an atom's nucleus, which determines the element's identity. All atoms of the same element have the same number of protons in their nucleus, hence they all have the same atomic number.
The number of the protons in the nucleus of a chemical element is equivalent to the atomic number; the atomic number define the position of this element in the periodic table (group, period). And from these we can suppose the chemical properties of this element.
The atomic number tells how many protons are in the atom, and the atomic mass tells how many neutrons and protons are in the atom together. Like Oxygen has an atomic number of 8. It also has 8 protons. It's atomic mass is 16. It also has 16 neutrons and protons. Helium's atomic number is 1. It only has 1 proton. It's atomic mass is 1 because it doesn't have any neutrons.
The atomic mass or mass of an atom is locaed at the bottom of a sqaure on the periodic table. The atomic mass= atomic number (protons/neutrons)+electrons. Enable to find the number of electrons you must
this elemnt has an atomic number that is double the atomic number of silicon?
the answer is that it is called a atomic number.
The atomic number is equal to the number of the protons in the atomic nucleus.
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
