What are the periods and groups in the periodic table?
The periodic table is organized into groups (vertical columns), periods (horizontal rows), and families (groups of elements that are similar). Elements in the same group have the same number of valence electrons.

Who created the periodic table?
The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train.
What is PubChem working with?
PubChem is working with IUPAC to help make information about the elements and the periodic table machine-readable.
Can periodic table games be used for grade?
The periodic table game available on this page is for entertainment purposes only, and should not be used to grade students on their knowledge of chemical elements.
Does the Modern Periodic Table Change? If So, How and Who Does That?
The periodic table as we know it today is managed by the International Union of Pure and Applied Chemistry, or IUPAC (eye-you-pack).
What are the P-block elements?
The p-Block Elements comprise those belonging to Group 13 to 18 and these together with the s-Block Elements are called the Representative Elements or Main Group Elements.
What is the modern periodic table?
The modern periodic table is the arrangement of all the known elements such that elements with similar characteristics are grouped. We know that the modern periodic table is made up of horizontal periods and vertical groups. In this article, we are going to study the similarities and periodicity of elements across the periodic table. We will study the different blocks: s-block, p-block, d-block, f-block and their characteristic properties, metals, metalloids, nonmetals, halogens, and noble gases.
How many metalloids are there?
There are 7 metalloids i.e. Boron, Silicon, germanium, arsenic, antimony, tellurium and polonium.
What type of electron enters in a D block?
In d-block elements, a valence electron enters in d-orbital.
Which elements of Group 1 and Group 2 belong to the S block?
The elements of Group 1 ( alkali metals) and Group 2 ( alkaline earth metals) which have ns1 and ns2 outermost electronic configuration belong to the s-Block Elements.
What are the shiny elements that form naturally below the surface of the Earth?
The lustrous or shiny elements that form naturally below the surface of the Earth are called Metals. These are elements having positive ions.
Which direction does the property of elements change in a horizontal row?
In a horizontal row, the property of elements changes from metallic on the left to non-metallic on the right.
Who created the modern periodic table?
The modern periodic table is based on the modern periodic law put forward by the English physicist Henry Moseley, which states that “the properties of elements are periodic functions of their atomic numbers”.
How many elements are in the periodic table?
The table below consists of 118 elements of the periodic table, sorted by atomic number, atomic weight, symbols, density, discovered year and the group.
What is the atomic number of an element?
The atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. The atomic number can provide insight into the electronic configuration of the element. For example, carbon has an electron configuration of [He] 2s 2 2p 2, since its atomic number is 6.
What is the number of protons in the nucleus called?
The number of protons in the nucleus is called the atomic number. The atomic number of each element is unique.
Why is the atomic number of each element unique?
While the atomic number always stays the same some elements have atoms with different atomic mass numbers. This is because some elements have a different number of neutrons in the nucleus.
How to find the mass of an element?
The number of protons and the number of neutrons shall determine the mass number of an element. Since the isotopes of an element have slightly different mass numbers, it calculates the atomic mass by obtaining the mean of the mass numbers for its isotopes.
How can periodic trends be observed?
Periodic trends in the properties of the elements can be observed down the groups and across the periods of the modern periodic table. Every chemical element has a specific atomic number, which provides insight into the number of protons present within its nucleus.
What are the horizontal rows on the periodic table called?
The horizontal rows on the periodic table are known as Periods.
Why are period 4 and period 5 called long periods?
Period 4 and period 5 are given the name long periods of the periodic table because there are 18 elements in these periods. The elements of the long periods are shown in tables below.
Why is period 1 the shortest period?
Period 1 of the periodic table is given the name shortest period because there are only two elements in period 1.
Why is period 2 called a short period?
Period 2 and period 3 of the periodic table are named as the short period because there are 8 elements in these periods.
Which period has the longest period?
Period 6 and 7: Longest period. Period 5 and period 6 are named as longest periods of the periodic table because there are 32 elements in these periods. The elements of the longest periods are shown in tables below.
How many energy shells does period 2 have?
All the elements of period 2 have two energy shells (or orbits).
