the Atomic number on Periodic Table is the identity of an element in the table , it gives the indications about Group, period and Block of elements it also predicts the chemical and physical properties of the element.
The period to which the element belongs
A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.
Yes!The elements are arranged in horizontal rows and vertical columns to represent what is called the periods on the periodic table.
"Na" is Sodium.
Elements in a row on the periodic table are called periods. They represent the number of electron shells an element's atoms have. Each period corresponds to the energy level of the electrons in an element's atoms.
No. they dont represent the periodic table.
the Atomic number on Periodic Table is the identity of an element in the table , it gives the indications about Group, period and Block of elements it also predicts the chemical and physical properties of the element.
Periods in the periodic table represent the number of electron shells necessary to fit all of the electrons. Once you fill the valence shell of an atom, the next electron must go in a new electron shell. This would constitute a new period on the periodic table.
the metals
The period number represents the highest principal quantum number of the valence electrons, or the energy level of the valence (outer) shell. So, a period represents atoms with the same core electron, or noble gas, configuration, and having the same number of occupied electron shells.
Helium is in the first period of the periodic table.
No. Xenon is not the first period of the periodic table. It is placed in the 5th period of periodic table.
