To finish calculating the frequency of an electromagnetic wave, you need the wavelength
Alkali metal - Group 1 metal
Alkaline earth metal - Group 2 metal
Iron triad - metal
Halogens - most are diatomic and are nonmetals - Cl2, Br2, I2
Noble gases - nonmetals and are not reactive due to full valence shell.
Boron group - metalloid
Oxygen group - oxygen molecule - a diatomic molecule composed of oxygen atoms, which are nonmetals.
HCl is the formula for hydrocloric acid
Answer : The given statement is, false.
Explanation :
Ionic product of water : It is defined as the product of the concentration of hydrogen ion and the concentration of hydroxide ion.
The mathematical expression will be,
![[H^+][OH^-]=10^{-14}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%5BOH%5E-%5D%3D10%5E%7B-14%7D)
When the concentration of hydrogen ion and hydroxide ion are equal then the solution is neutral and the value will be,
. And the pH of the solution is, 7.
When the concentration of hydrogen ion is greater than
then the solution is acidic in nature. And the pH of the solution is, less than 7.
When the concentration of hydrogen ion is less than
then the solution is basic in nature. And the pH of the solution is, greater than 7.
Hence, the given statement is false.
