Is calcium reactive or nonreactive? What is the atomic mass of iron? What is the atomic number of silicon? What is the electronegativity of magnesium? What is the atomic number for tellurium? What is the electronegativity of silicon?
Helium doesn’t catch fire. It is an inert gas used in liquid form as a coolant in some industries. Helium is highly stable and non-reactive in both gaseous and liquid forms. It has the lowest melting and boiling points and does not burn. Noble gases, like helium, don’t burn in oxy...

Because it is chemically inert, it is also used as a gas shield in robotic arc welding and as a non-reactive atmosphere for growing silicon and germanium crystals used to make electronic semiconductor devices. Liquid helium is often used to provide the extremely low temperatures required in ...
The halogen is chemically reactive, and combines with this tungsten deposit on the glass to produce tungsten halides, which evaporate fairly easily. When the tungsten halide reaches the filament, the intense heat of the filament causes the halide to break down, releasing tungsten back to the ...
Why are alkali metals very reactive? Why are arc sources often blanketed with a stream of an inert gas? Why is the molecule of Li2^2- a non-existent? Why is helium referred to as inert? Why is that rotation is restricted at the double bond, why rotates freely at the single bond?
What is the most reactive non-metallic atom? What is a covalent bond and ionic bond? What is the least electronegative element? Which is the strongest of the atomic bonds? What is a polar covalent bond? How is electron affinity different from electronegativity?
