The little number under the Element symbol is known as the Atomic Number. The Atomic Number represents the number of protons located at the atom's nucleus. It also tells how many electrons are in the atom, considering the atom is a stable particle, the number of electrons and protons are equal in an atom at its normal state.

Elements a compound contains and the exact number of the atoms of each element in a unit of that compound is called what?
That is called a formula.
Why are elements on the periodic table called families?
Each family of elements has its own set of characteristics that each of the elements possess.
What elements is equal to atomic number?
All elements each have an unique atom number (1 to about 104) which equals the number of protons in its nucleus.
Why where the lanthanide and actinide elements droped out of order on the periodic tabel?
The vertical columns of the periodic table are arranged to contain elements that have similar chemical and physical properties.The two rows at the bottom (called the Lanthanide and Actinide series) are elements that would all fit into group IIIB, in periods (horizontal rows) 6 and 7. since there is only one spot on the chart for all the elements in each series, they are listed separately at the bottom of the table.
WHEN DO ELEMENTS DIFFER FROM EACH OTHER?
The difference is made by the number of protons, specifi for each element.
What determines the number of electrons found in each period In the periodic?
there are more electrons in the elements on the bottom of the table.
Why is magnesium different from other elements?
All elements are different from each other, that is why they are called elements. They have a different number of subatomic particles making them different.
Elements a compound contains and the exact number of the atoms of each element in a unit of that compound is called what?
That is called a formula.
What are elements in a column called?
The elements in the 8 main columns of the Pperiodic Table are called Groups. Groups 1 and 2 are separated from Groups 3 to 8 by a block of elements called the Transition Series and the columns in this series have no specific names.
What do elements have the same number of?
Elements have the same number of protons in each atomic nucleus.
Why are elements on the periodic table called families?
Each family of elements has its own set of characteristics that each of the elements possess.
What makes the elements in the periodic table different from each other?
The number of protons in the nucleus or the number of electrons surrounding the nucleus. This number is also called atomic number of the element.
What is the fundamental difference between elements?
The elements are all very different from each other in many ways! However, what uniquely defines the identity of each element is the number of protons in the nucleus of the atom, also called the atomic number.See the Related Questions to the left or more information about the elements.
How are elements arranged in the current periodic table?
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.
What tells you the number atoms of each elements?
atomic number
What is each number in a number pattern called?
Each number in a number pattern is called a Term.
How are the elements in each period alike?
the number of protons
