Is there an element 123?
Please visit the Tellurium element page for information specific to the chemical element of the periodic table.
What is the atomic number of 8 protons?
Oxygen
Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!
Does oxygen have 8 electrons?
Now you can figure out how many electrons, protons and neutrons Oxygen has: Atomic number (which is always the smaller of the two numbers) is 8. Hence 8 protons. Because the atom is neutral, there are also 8 electrons.
What is Group 8 called?
the noble gases
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). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
Is Group 8 a metal?
Group 8 is a group of chemical elements in the periodic table. It consists of iron, ruthenium, osmium and hassium. They are all transition metals. Like other groups, the members of this family show patterns in electron configuration, especially in the outermost shells, resulting in trends in chemical behavior.
Is element 119 possible?
Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon.

Why is tin called tin?
The name derives from the Anglo-Saxon tin of unknown origin. The symbol Sn is derived from Latin stannum for alloys containing lead. The element was known in prehistoric times. Archaeological evidence suggests that people have been using tin for at least 5500 years.
Is element 140 possible?
According to this, Corbomite (Ct) is a chemical element with atomic number 140. However, in real-life science, element 140 has yet to be identified.
Why is the atomic number of oxygen 8?
The atomic number of oxygen is 8. The mass of an atom is given by the sum of the number of protons and neutrons present in the nucleus. Also, the atomic number is the number of protons present in the nucleus. Since the number of neutrons present in oxygen is 8, hence the atomic number of O is 8.
What is the valence of oxygen 8?
Atomic Number of oxygen is 8. electronic Configuration of oxygen= 2, 6. So the valency is 8-6 = 2.
What is the element with 8 electrons?
neon
Similarly, neon has a complete outer 2n shell containing eight electrons. These electron configurations make helium and neon very stable.

Is Group 8 noble gases?
Group 8A — The Noble or Inert Gases. 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). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
What properties does Group 8 have?
They are inert gases located on the right of the periodic table. They have a full-set of valence electrons, so they’re stable. They are colorless, odorless and tasteless. They have low melting and low boiling points.
