These periodic tables use accurate data for name atomic number element symbol atomic weight and electron configuration obtained from the International Union of. When the elements are thus arranged there is a recurring pattern called the periodic law in their properties in which elements in the same column group have similar properties.

Common Properties Abundance in Earth's Crust The simple answer: Atomic size increases down the group (from top to bottom) and it decreases across the period (from left to right). Now the helium atom is located at the far top-right side of the Periodic table. So according to the Periodic trends, the size of helium atom is the smallest in entire Periodic table.

Learn the properties of some of the groups of the periodic table. In this video we will learn about Alkali Metals, Alkaline Earth Metals, Transition Metals, The discovery of the periodic recurrence of similar properties among the elements led to the formulation of the periodic table, in which the elements are arranged in order of increasing atomic number in rows known as periods and columns known as groups. Elements in the same group of the periodic table have similar chemical properties.

The group number in the periodic table represents number of valence electrons of the elements in a certain group. For example, all the elements in Group−1 have 1 electron in their outer most shell. Furthermore, what are the 7 groups of the periodic table?

Easy Game Level. When shown an element name, find the corresponding element atomic number and symbol in the periodic table as quickly as you can! Medium Game Level Group-1 (hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium) and group-2 (beryllium, magnesium, calcium, strontium, barium, and radium) belong to these classes with valence shell electron configuration, ns 1→2, where n = principle quantum number, or the number of periods. 2019-02-21 2017-03-12 2012-10-24 2020-02-16 A group is a vertical column of the periodic table, based on the organization of the outer shell electrons.

Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.

The rows of the table are called periods. A period is a group of elements whose properties are basically the At first glance, the periodic table looks very complex. In fact it is a large The elements are arranged in order of their atomic number.

We already know that all the elements in periodic table are arranged serially according to their atomic numbers. There are 18 groups and 7 periods.
