When an atom or molecule accepts or looses an electron or electrons it gets either negative charge (when electrons gained) or a positive charge (when looses electron). The negative ion is called Anion and positve ion is called the Cation. An Ion can be Atomic or Polyatomic.
Example:
Sodium when looses one electron forms a cation i.e. Na⁺
Chlorine when gains one electron forms an Anion i.e. Cl⁻
Result:
<span>A negative ion (Anion) differ from an uncharged atom of the same element in the number of electrons. An anion contains more electrons than its corresponding Neutral Element.</span>
Explanation:
compound is already together use your brain man you take multiple things. to make lemonade aka a mixture of powder and water cmon man u gotta think about it logically
think about like this a bartebder asjs you what drink your having what is he going to do next ? hes going to make the drink so you can have another right? yha
observe what happens next
the bartender grabs a cup and goes to the ice and scoops it up he takes a bottle of vodka and puts it into the shot cup "a preset cup for alcohol measurement " he takes stawberry puraee (strawberry mix) and pyrs it into the drink and mixes it around by shaking it . puts a extractor on top of it and takes a glass and pours the drink in front of you into the glass. you dont see the vodka in there do you ? no you dont because its mixed in there same thing with lemonade.

Answer:
Option C is correct.
The minimum amount of material that is needed for a fission reaction to keep going is called the critical mass.
Explanation:
Nuclear fission is the term used to describe the breakdown of the nucleus of a parent isotope into daughter nuclei.
Normally, the initial energy supplied for nuclear fission is the energy to initiate the first breakdown of the first set of radioactive isotopes that breakdown. Once that happens, the energy released from the first breakdown is enough to drive further breakdown of numerous isotopas in a manner that leads to more energy generation.
But, for this to be able to be sustained and not fizzle out, a particular amount of radioactive material to undergo nuclear fission must be present. This particular amount is termed 'critical mass'
Hope this Helps!!!
The car has greater momentum because it has more mass than a bike, even if they have the same speed. I hope this helped! :-)
