Answer: The given statement is false .
Explanation:
Noble gases are least reactive elements in the periodic table. Noble gases have fully filled stable electronic configuration which the reason of their inert and lest reactive nature.
For example : Helium. Neon, argon etc.

Answer:
1.21 times
Explanation:
The energy of a wave is proportional to the square of the amplitude of the wave.
Mathematically:
where
E is the energy of the wave
A is its amplitude
In this problem, the amplitude of the wave increases by a factor of 1.1; it means that the new amplitude can be written as
Therefore, this means that the energy of the wave increases by a factor:
Therefore, the energy of the wave increases by a factor 1.21.
Answer:
magnification and resolution
Explanation:
Two parameters are especially important in microscopy: magnification and resolution. Magnification is a measure of how much larger a microscope (or set of lenses within a microscope) causes an object to appear.
