The major difference is that the first one is right and the second one is wrong! Both [tex](1)^2[/tex] and [tex](-1)^2[/tex] are equal to 1 so both of those is [tex]\sqrt{1}[/tex]. And [tex]\sqrt{a}[/tex] is defined as the positive number, x, such that [tex]x^2= 1[/tex].bergausstein said:can you tell the difference
$\displaystyle \sqrt{(1)^2}=1$$\displaystyle \sqrt{(-1)^2}=-1$
A radical is a chemical species that contains an unpaired electron, making it highly reactive and unstable.
The main difference between a radical and a regular molecule is the presence of an unpaired electron in the radical, which makes it highly reactive and unstable compared to regular molecules.
Radicals play a crucial role in many chemical reactions. They are highly reactive and can initiate chain reactions, making them important in the production of many industrial and biological processes.
Radicals are formed when a covalent bond breaks unevenly, leaving one atom with an unpaired electron. They can also be generated through the absorption of light or heat, or through the reaction of two molecules.
Some common examples of radicals include the hydroxyl radical (OH), the methyl radical (CH3), and the nitric oxide radical (NO). These radicals play important roles in atmospheric chemistry, organic synthesis, and biological processes.
