Explanation: Similarity: Atomic radius increases down the group for both. However, when we move from the left to right in a period, this polarizing power keeps on increasing. The alkali metals burn vigorously when heated and placed in a gas jar of oxygen. Group 1 elements get more reactive down the group becasue with each step down the group the number of full electron rings increases by 1 and the outermost electron is further away from the positive nucleus. The Facts . Periods 4 and 5 have 18 elements. The other three elements in this group are active metals, but they are so scarce they are of limited interest. electronegativity and reactivity decreases down the group. Other Alkali Metals: Alkali metals are group 1 elements excluding hydrogen. The first group is the alkali metals; the second is called the alkali earth metals, the d block of elements are known as the transition series. © copyright 2003-2020 Study.com. All rights reserved. Most metals are too reactive to exist on their own in the ground. is less reactive and is also harder. Similar chemical properties. The key difference between group 1 and group 2 elements is that all group 1 elements have unpaired electrons in their outermost orbital, whereas group 2 elements have paired electrons in their outermost orbital. 5 6 7. Copyright © 2020 Multiply Media, LLC. This page looks at the reactions of the Group 1 elements - lithium, sodium, potassium, rubidium and caesium - with water. 2. Although often listed in Group 1 due to its electronic configuration, hydrogen is not technically an alkali metal since it rarely exhibits similar behavior. The alkali metals include: lithium, sodium, potassium, rubidium, cesium, and francium. Services, The Periodic Table: Properties of Groups and Periods, Working Scholars® Bringing Tuition-Free College to the Community. Explanation: Similarity: Atomic radius increases down the group for both. (b) (i) All the chemically similar elements will have same valence electrons. Relevance. These similarities and dissimilarities should be known while we study periodic table elements. It uses these reactions to explore the trend in reactivity in Group 2. The key difference between periods and groups is that the periods are horizontal rows whereas the groups are the vertical columns in the periodic table of chemical elements.There are 7 major periods and 18 groups in the periodic table of elements. 1 metals have ONE valence electron and group 2 have TWO valence Recommended: Please solve it on … Qualifications: Any graduate from recognized university. This makes a great difference in how they react This page looks at the reactions of the Group 1 elements - lithium, sodium, potassium, rubidium and caesium - with water. Properties: Silvery metals. The group 1 elements have low melting points and densities, so sodium is a typical group 1 element. Difference: For group 2, as you go down the group melting point decreases while in group 7, melting and boiling points increase down the group. The difference for the respective groups are as follows: Group1 : It is for higher position jobs like DCP,Assistant Commissioner,Assistant Director of Rural Development department, etc. Such groups include alkali metals , alkaline earth metals, transition metals (including rare earth elements or lanthanides and also actinides), basic metals, metalloids or semimetals, nonmetals, halogens, and noble gases.
