atoms that occur as 2 atom molecules (N,O,F,Cl,Br,I,H)
================
The Rule of Seven refers to seven specific elements on the Periodic Table that share certain properties. These elements are hydrogen (H2), Oxygen (O2) Nitrogen (N2) Flourine (F2), chlorine (Cl2), bromine (Br2) and iodine (I2).
The positions of these seven elements form the shape of a 7 on the periodic table. The properties they share are these: They have the greatest stability in the diatomic (2 atom) form, and they are bonded covalently.
The elements that make up Group 18 on the Periodic Table are caleed noble (or inert) gases.
The periodic table lists the elements and not compounds. Butane, C4H10, is an organic molecule / compound and hence is not present on the periodic table. The elements that make up butane (carbon and hydrogen) are present on the periodic table. Carbon: group 14, period 2 Hydrogen: group 1, period 1 Besides, group 2 elements are alkaline earth metals.
Potassium citrate does not appear on the periodic table. Only elements are found on the periodic table, and potassium citrate is a salt made from potassium (an element) and citric acid (a compound make of several elements). Even though it isn't found in the periodic table, it can still be classed as a SALT.
There are 32 elements in the 6th period of the periodic table.

The elements that make up Group 18 on the Periodic Table are caleed noble (or inert) gases.
The answer is Group 17 Halogens.
The group on the right side of the periodic table are the noble gases.
The periodic table lists the elements and not compounds. Butane, C4H10, is an organic molecule / compound and hence is not present on the periodic table. The elements that make up butane (carbon and hydrogen) are present on the periodic table. Carbon: group 14, period 2 Hydrogen: group 1, period 1 Besides, group 2 elements are alkaline earth metals.
Nitrogen makes 78% of the air. It also belongs to Group-15 of periodic table of elements.
Lead is in the group 14 of the Periodic Table of elements.
The transition metals are often used as ore formers in the periodic table of elements. This is because they have properties that make them suitable for forming metallic ores found in the Earth's crust.
the Noble Gases
118 elements.
Group-2 elements or alkaline earth metals(i.e.Be,Mg,Ca,Sr,Ba,Ra) makes up earth metals in periodic table
To make study of elements easier.To classify elements.
Elements in the Periodic Table that are not reactive are called the Noble Gases.
