For example, copper is used for electrical<span> wiring because it is a </span>good conductor of electricity<span>. </span>Metal<span> particles are held together by strong metallic bonds, which is why they have high melting and boiling points. The free electrons in </span>metals<span> can move through the </span>metal<span>, allowing </span>metals<span> to conduct </span>electricity<span>.</span>
Electrons in an atom are held there by the force of attraction exerted by the positive charge of the nucleus on the negative charge of the electron. Energy is required to remove an electron from atom to overcome this attractive force.
Atoms must have equal numbers of protons and electrons. So to answer your question, yes protons and electrons are the same number.
V1/T1 = V2/T2, so
<span>V2 = V1 * T2 / T1 </span>
<span>V2 = 54.2 L * 345 K / 115 K </span>
<span>V2 = 163 L</span>
True because of the less energy the more stable
