Atoms with 8 valence electrons (or obeying octet rule) have more stability and are generally chemically inert.
Iron is Period 4 going horozontal on the periodic table.
Iron is placed in group-8 in the periodic table. Its symbol is Fe.
There are 18 groups and 7 periods in the modern periodic table.
The octet rule does not always refer to a stable arrangement of 8 valence electrons because some atoms can accommodate more than 8 electrons in their valence shell (expanded octet), such as elements in Period 3 and beyond in the periodic table. Additionally, some molecules, like radicals or species with an odd number of electrons, may not satisfy the octet rule but can still be stable due to resonance or other factors.
Iron is located in Group 8 (VIII) on the periodic table, also known as the Transition Metals group.
Oxygen is number 8 in the periodic table.
It means 8 Tentacles of an Octopus. Octo means 8.
Group 8 a doesn't exist.
There aren't 8, there are about 112
The periodic table address for oxygen is 8, as it has 8 protons in its nucleus. Oxygen is located in Group 16 (or 6A) and Period 2 of the periodic table. It has an atomic number of 8.
There are 8 elements in the third period of periodic table. The elements belong to group-1,2,13,14,15,16,17 and 18
Iron is Period 4 going horozontal on the periodic table.
Iron is placed in group-8 in the periodic table. Its symbol is Fe.
Iron oxide is not on the periodic table because it is a compound and the periodic table is only for elements.The elements that make up iron oxide (iron and oxygen) can be found on it however.Iron is near the top and middle of the periodic table and has the symbol Fe.Oxygen is near the top-right corner and has the symbol O.
It is group 8.
In the periodic table, "K" represents potassium, which has the atomic number 19. The "O" in "KO" typically refers to oxygen, with the atomic number 8. However, "KO" is not a standard notation in the periodic table; it might refer to potassium oxide (K₂O) in chemical contexts, where potassium combines with oxygen.
There are 18 groups and 7 periods in the modern periodic table.
