What is Group 8 of the periodic table?
Group 8 is a group (column) of chemical elements in the periodic table. It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs). They are all transition metals. Group 8 (current IUPAC) should not be confused with “group VIIIA” in the CAS system, which is group 18 (current IUPAC), the noble gases.

What are the trends in group 8 elements?
Noble Gases: Trends
- The noble gases have weak van Der Waals forces within their atoms.
- As non-metals, the noble gases have low boiling points.
- Atomic mass increases moving down the column.
- The density of the noble gases also changes moving down the column.
What is the name given to group 8 elements?
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
What is the rarest element in the universe?
Astatine
Astatine is the rarest naturally occurring element.
What is the most common element in the human body?
Oxygen
Oxygen is the most common element in the human body, comprising approximately 65.0% of body mass. Most of the oxygen present is found in the form of water.
What is the most useful element?
Silicon is one of the most useful elements to mankind. Most is used to make alloys including aluminium-silicon and ferro-silicon (iron-silicon).
What are the 8 most common elements?
The 8 most common elements in Earth’s crust (by mass): 46.6% Oxygen (O) 27.7% Silicon (Si) 8.1% Aluminum (Al) 5.0% Iron (Fe) 3.6% Calcium (Ca) 2.8% Sodium (Na) 2.6% Potassium (K) 2.1% Magnesium (Mg) The picture on the left shows where these elements are located within the periodic table.
What are the 8 groups of elements?
The elements in a group have similarities in the electronic configuration of their atoms, and thus they exhibit somewhat related physical and chemical properties. The periodic table has eight main groups: 1, 2, 13, 14, 15, 16, 17, and 18 (previously numbered Ia, IIa, IIIa, IVa, Va, VIa, VIIa, and 0, respectively).
What are the 8 families of the elements?
Families on the periodic table include, in addition to noble gases and halogens, the alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides. The nonmetals form a loosely defined cross-family grouping, as do the metalloids.
What are the 8 most common elements on Earth?
The earth is composed of various kinds of elements. About 98% of the total crust is made up of eight elements as oxygen, silicon, aluminium, iron, calcium, sodium, potassium, and magnesium. The rest is constituted by elements like titanium , hydrogen, phosphorous, manganese, sulphur, carbon, nickel and others.
