True or False: The no. of protons and the no. of electrons in an atom of an element is always the same.
True or False: The no. of protons and the no. of electrons in an atom of an element is always the same.
Statement is False
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral.
But in case an atom tends to form an ionic bond with any other atom, it either loses or gains electrons (the number of electrons lost or gained depends on the number of electrons present in the valence shell of the atom) and becomes ionized. In this case, the number of electrons and protons differ.
Thus, in an ionized atom or simply an ion, the number of protons and electrons are not the same but in a neutral atom, they are.
Example: Na is electrically neutral due to the equal number of protons and electrons.
Na+ is not electrically neutral as it has 11 protons and 10 electrons.
