================
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.
these are seven horizontal rows called PERIODS. Showing number of orbits in atoms of these periods.

There are 7 periods in the periodic table.
These elements are: manganese, technetium, rhenium, bohrium.
The horizontal rows on the periodic table are called periods.
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.
Fluorine is an element, in group 7 of the periodic table.
The elements that make up Group 18 on the Periodic Table are caleed noble (or inert) gases.
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.
Group 18 is the noble gases, the last group on the periodic table. The elements are Helium, Neon, Argon, Krypton, Xenon, and Radon. These elements have a full outer shell and are virtually nonreactive.
The answer is Group 17 Halogens.
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.
The group on the right side of the periodic table are the noble gases.
Fluorine is an element, in group 7 of the periodic table.
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 elements that make up Group 18 on the Periodic Table are caleed noble (or inert) gases.
