The top number in each element means the number of protons and electrons in the atom of that element.
Within each element square, information on the element's symbol, atomic number, atomic mass, electronegativity, electron configuration, and valence numbers can be found. At the bottom of the periodic table is a two row block of elements that contain the lanthanoids and actinides.
I'm assuming you mean "how can you find an element on the periodic table?" The periodic table is strategically placed. You can either look for the atomic number (the number at the top-- the number of the protons in one atom), or you can just look for the Element Symbol. The periodic table from left to right is sorted by increasing atomic number. The periodic table from top to bottom is sorted by increasing number of energy levels (the levels in which the electrons are in).
The atomic number is the number of protons in the element. For example calcium has 20 protons, so that means it has an atomic number of 20. You can find the element's number on the periodic table; its usually the number on top of the element's symbol
Usually on the very top of every element.
First of all, you spelled "element" wrong. And to find the Atomic Number of an element, you look at the number on the top of the element in the Periodic Table. For example, Hydrogen is 1, 1 is its atomic number. The atomic number is also the number of protons and electrons in an 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.
Elements are arranged in order of increasing atomic number. The atomic number is the number found at the top of each box on the Periodic Table. The atomic number is the number of protons in the nucleus of each atom of each element.
Iodine has 53 protons. The number of protons is equal to the atomic number which is the number at the top of each element that is bolded.

The Atomic Number
The Periodic Table lists the elements in the order of there atomic numbers. The number on the top of each square is the atomic number of the element.
The number of protons in an element is the atomic number, which can be found in the top right corner of the box containing the element.
The oxidation number is located in the top right-hand corner of each element box; for many elements there is more than one.
The number at the top of an element square is referred to as an atomic number. This number provides you with multiple information such as the number of protons and electrons the element has, and with the atomic number it is easier to locate the element on the periodic table. In this case, Carbon's atomic number would be 6, as well as how many protons and electrons are in its nucleus.

The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
