The elements in the same group have 2 things in common. For example; Example #1 Let us consider group 1 elements. All the elements of 1st group (H, Li, Na, K, Rb, Cs, Fr) have one valence electron. In other words, these elements have only one electron in their outermost orbit. Also, the elements lying … Read more
The group number tells you the total number of electrons present in the outermost orbit of an atom. In other words, group number tells you the number of valence electrons of an atom. For example, Let us consider group 1 of the Periodic table. Group 1 indicates that the elements lying in that group have … Read more
The periods on the Periodic table represents the number of shells (or orbits) of an atom. For example, Period 1 represents that the elements lying in that period have only 1 orbit. There are 2 elements in the first period i.e hydrogen (H) and helium (He). These elements have only 1 electron orbit. Similarly, period … Read more
Inner transition metals are located in the two rows at the bottom of the periodic table. From above image, you can easily find where Inner Transition Metals are located on Periodic Table. These two rows at the bottom of the Periodic table are called; But wait… A question for you. Do you know why are … Read more
The transition metals are located in the middle of the Periodic table from group 3 to group 11. From the above image, you can easily see where are Transition Metals located on the Periodic Table. According to some chemists, the d-block elements are known as transition elements. But wait… this is not completely true. I’ll … Read more
Noble gases are located in the right most group of the Periodic table (i.e group 18). This above image exactly shows you where are noble gases located on the Periodic table. There are total 6 known noble gases on the Periodic table. Oganesson (Og) is predicted to have similar properties like Noble gases, but it … Read more
Do you know why are group 1 elements called alkali metals? Here I will explain to you the exact reason why they are called so. Here is the reason: These are the alkali metals. When these metals react with water, they form alkalis (i.e strong base). Let me explain this to you with examples. Here … Read more
Have you ever wondered why are group 2 elements called alkaline earth metals? You will get the exact answer here (with examples) Here is your answer: When alkaline earth metals (i.e Be, Mg, Ca, Sr, Ba and Ra) react with water, they form hydroxides which are alkaline in nature (or basis in nature). Wait, I’ll … Read more
Alkaline earth metals are found in the 2nd group of the Periodic table. This above image shows you where are alkaline earth metals found on the Periodic table. Alkaline earth metals are located just next to the alkali metals. Alkaline earth metals includes; Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba) and Radium … Read more
Alkali metals are located in group 1 on the left side of the Periodic table. Alkali metals include: Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs) and Francium (Fr). This above image clearly shows you where are Alkali metals located on the Periodic table. But hold on… There are lot more things you … Read more
