The atomic number of an elemnt tells you how many protons are in the nucleus and therefore how many electrons thare are in a neutral atom.
The mass number is the toal of protons and neutrons.
An element's atomic number tells us the number of protons in an atom of that element. It is used to uniquely identify the element and determine its placement on the periodic table. The atomic number also corresponds to the number of electrons in a neutral atom of that element.
It tells you the number of cations in the outer energy level of the element's atomic mass
All elements have protons and electrons. All but hydrogen have neutrons. All elements have isotopes which vary in neutrons but have the same amount of protons as the original element. Different elements never have the same amount of protons so scientists gave these elements their "atomic number" based on the amount of protons the element has. atomic number = amount of protons.
No, the mass number of an element represents the total number of protons and neutrons in its nucleus. To find the number of protons, you would look at the element's atomic number, which is the smaller number on the element's symbol.
If you know the atomic no. and atomic mass, then the no. of electrons, no. of protons and no. of neutrons can also be determined. Atomic No.=No. of electrons = No. of protons. No. of neutrons=Atomic mass-Atomic no. Also, by no. of electrons you can determine its valency and the no. of valence electrons.
atomic number tells us the number of protons and electrons in the given atom. As Atomic No. = no. of protons = No. of electrons
The atomic number of an element tells you the number of protons in the nucleus. It is the whole number found above the element symbol in the periodic table. Each element has a unique atomic number that corresponds to the number of protons in its nucleus.
The atomic number tells you the number of protons in the nucleus of an atom of the associated element.
The atomic number of the element refers to the number of protons of an atom: all atoms of an element have this number of protons. A neutral atom of the element will have the same number of electrons.
An element's atomic number tells us the number of protons in an atom of that element. It is used to uniquely identify the element and determine its placement on the periodic table. The atomic number also corresponds to the number of electrons in a neutral atom of that element.
The atomic number of an element tells you how many protons there are in each nucleus of each atom of the element. On the periodic table, you find the atomic number at the top of the box for each element.
The atomic number of an element tells you how many protons there are in each nucleus of each atom of the element. On the periodic table, you find the atomic number at the top of the box for each element.
The element with 50 protons on the periodic table is tin, which has the atomic number 50.
Atomic number and it also tells the number of protons and electrons in an atom it is on top of the element symbol.
The number of protons in the nucleus of each atom of the element.
It tells you (1) how many protons are in the element, and (2) what the element is since all atoms of an element will have the same number of protons.It's D. The number of protons in its atoms.It tells how many protons/electrons that element has.
The atomic number, which is located at the top of each element square in the periodic table, tells you the number of protons and electrons in an atom of that element.
