How do you find the position of an element on the periodic table in Class 10?

Elements are placed in groups according to their valence electrons and placed in periods according to the number of shells present in them. Helium has valence electrons equal to 2, but it is placed in group number 18 because it is a noble gas and has completely filled outermost shell.

How the position of an element in the periodic table is determined from its electronic configuration?

the number of circles in the electronic configuration of an element is represented in the periodic table as the period number that element is situated in. the number of electrons in the outermost shell of an element is represented in the periodic table as the group number that element is situated in.

What is the position of sodium in periodic table?

sodium (Na), chemical element of the alkali metal group (Group 1 [Ia]) of the periodic table. Sodium is a very soft silvery-white metal….sodium.

How will you predict the period number occupied by an element?

-Now, to determine the period in which the element is placed, we need to look at the principal quantum number of the valence electron. If the element is in s block, then the group number is equal to the number of valence electrons.

What is the position of chlorine in periodic table?

Chlorine is in group 17 of periodic table, also called the halogens, and is not found as the element in nature – only as a compound. The most common of these being salt, or sodium chloride, and the potassium compounds sylvite (or potassium chloride) and carnallite (potassium magnesium chloride hexahydrate).

What is the position of potassium in periodic table?

19th
Potassium is the 19th element on the periodic table. It is located in period 4 and group 1.

How can the position of an element be used to predict its properties?

The Periodic Table can predict the properties of new elements, because it organizes the elements according to their atomic numbers. They hope that the two nuclei at the centre of these atoms will fuse and form a heavier nucleus. When these heavy elements form, they are usually highly unstable.

What is the relationship between atomic number and the position of an element?

The atomic number of an element was originally just its position on the periodic table. After the discovery of protons , scientists realised that the atomic number of an element is the same as the number of protons in its nucleus .

What is the position of fluorine in periodic table?

Fluorine (F) is the first element in the Halogen group (group 17) in the periodic table. Its atomic number is 9 and its atomic weight is 19, and it’s a gas at room temperature.

What is helium on the periodic table?

helium (He), chemical element, inert gas of Group 18 (noble gases) of the periodic table. The second lightest element (only hydrogen is lighter), helium is a colourless, odourless, and tasteless gas that becomes liquid at −268.9 °C (−452 °F).

What is Neon on the periodic table?

neon (Ne), chemical element, inert gas of Group 18 (noble gases) of the periodic table, used in electric signs and fluorescent lamps. This element is more abundant in the cosmos than on Earth.
