Answer:
Cuando un átomo neutro gana uno o más electrones, el número de electrones aumenta mientras que el número de protones en el núcleo permanece igual. El resultado es que el átomo se convierte en un anión, un ion con una carga neta negativa.

Sorry but I do not the answer to help you but I will advise you to look in internet for better answer and secondly I think your cheating while doing paper
The dilution formula can be used to find the volume needed
c1v1 = c2v2
Where c1 is concentration and v1 is volume of the concentrated solution
And c2 is concentration and v2 is volume of the diluted solution to be prepared
c1 - 0.33 M
c2 - 0.025 M
v2 - 25 mL
Substituting these values in the equation
0.33 M x v1 = 0.025 M x 25 mL
v1 = 1.89 mL
Therefore 1.89 mL of the 0.33 M solution needs to be diluted up to 25 mL to make a 0.025 M solution

The correct option is A.
Metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. The malleability of metals refers to their ability to withstand bending and hammering without breaking. Metals are not dull, neither are they brittle, those are the properties of non metals.
