What else can I help you with?
What is A Grade 8 Science Experiment powered by liquids or gases?
Gases.
What is the name given to the elements in group 8?
=NOBLE GASES=
What is the noble gases structure?
8 outer electrons s2p6
What are the column 8 elements called?
Column 8 elements are known as the noble gases or inert gases. They include helium, neon, argon, krypton, xenon, and radon. These elements have a full outer electron shell, making them stable and nonreactive.
Why were the noble gases at one time called the inert gases?
Noble gases are gases and have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and called inert gases.
What is it called when an electron has 8 electrons in its outer shell?
When an electron has 8 electrons in its outer shell, it is considered to have a stable configuration known as an octet. This stable configuration is achieved by filling the outermost energy level with 8 electrons, following the octet rule.
How many electrons in the outermost energy level of noble gases?
8
Which is the noble gases does not posses 8 electronS in its outermost shell?
it is Helium.
What has 8 electrons and is stable?
the noble gases in the column on the far right
Why do the noble gases in group 8 not needed to react-they are happy?
Noble gases have completely filled valence orbitals. Hence they are chemically inert.
What are characterisatics of noble gases?
Noble gases have completely filled valence orbitals. Helium has 2 valence electrons, whereas other noble gases have 8. They are generally chemically inert at STP.
How many valence electrons do noble gases have?
Inert gases have 8 valence electrons. This is why they are inert, they have a complete octet formed of electrons and are in their lowest energy configuration.
