Yes. Atoms have protons (positive charges) and electrons (negative charges). However, quite often it is the negative charges (the electrons) that carry the current. In any case, the net charge in a conductor is usually zero (it is neutral) - the electrons simply go in one end and out the other, but the total number of electrons will doesn't change in normal circumstances, whether there is a current or not.

What is an example of an electrically neutral atom?

An example of an electrically neutral atom is carbon. Carbon has 6 protons and 6 electrons, giving it an equal number of positive and negative charges, which cancels out to make it electrically neutral.


Are metalloids electrically conductive?

Yes, metalloids have properties of both metals and non-metals. They are semiconductors, meaning they can conduct electricity to some extent, but not as well as metals. Their conductivity can be modified by controlling impurities or introducing dopants.


When the number of electrons and protons in a sample of matter are equal the matter is?

neutral. Positive and negative charges cancel each others.


How many valence electrons do metals have?

Metals as found in the Periodic Table have no "extra" electrons. They are electrically neutral because they have the same amounts of protons and electrons or + and - charges respectively. However metals react with non-metals to form Ions, cations to be more precise, in this case they actually lose electrons resulting in a positive charge. In other words, metals never have "extra" electrons, they either have a neutral charge or they are lacking electrons and have a negative charge.


Why is an atom electrically neutral?

An atom is electrically neutral because it has the same number of protons (positively charged) in its nucleus as electrons (negatively charged) surrounding the nucleus. This balancing of positive and negative charges within the atom results in an overall neutral charge.
