The metallic character of an element is determined by how readily it loses electronic elements to lose electronics most easily have the greatest metallic character a which group has the greatest metallic character B which group has the lowest at tallaght character C which is the relationship between metallic character and I nice ation energy

i dont know

explanation:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

i wish i could but this one is weird give me abc and i can solve it.
