Noble gases are inert gases true or false?
TRUE (apex)
True or false noble gases are inert gasses?
Noble gasses are historically known as inert gasses - so true
Is it true or false that Noble gases are inert gases?
Noble gases are inert gases because of a completely filled valence shell,hence they need not to satisfy their valency.
Why are Group 8A elements known as noble gases?
The grup 8 elemnts are quite unreactive- the term noble was I think coined for gold and other unreactive metals- and the adjective got re-used- they were once called the inert gases- but this is no longer true as unstable reactive compounds have been made for Argon and the heavier members of the group.
What one statement is true about noble gases?
Noble gases 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 generally donot form compounds under normal conditions.

Why are the inert gases called by this term?
The Noble gases were known as inert gases because it was believed that they were completely unreactive. This is no longer true as scientists have discovered compounds containing noble gas elements.

What are the properties of noble gasses?
Noble gases have a minimum tendency to lose or gain electrons and thus engage in chemical reactions. Elements are more likely to combine when it leads to the outermost electron shell becoming full. For the noble gases the outermost electron shell has eight electrons, which is to say that it is already full (this is true for all except helium, which has 2 electrons in its only shell, but again this means the outermost shell is full). Therefore it is difficult for the atoms of a noble gas to combine with other atoms to form a compound. For this reason we say that the element is "inert" (as in does not react), and indeed the noble gases were known as the inert gases before it was discovered that it is possible for the heavier "inert gases" to form compounds.

What is true of noble gases?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
What is true about the highest occupied s and p sublevels for the noble gases?
they are all completely filled in the case of noble gases
Is it true that all elements are gases?
It is false.
What statement is true about the atoms in helium?
Helium has two natural isotopes and is an inert noble gas.
