Final answer:

A neutral atom has the same number of protons and electrons to maintain a balanced overall charge, with protons having positive charges and electrons having negative charges. The atomic number represents the number of protons, which equals the number of electrons in a neutral atom. Structural stability is achieved through the attraction between negatively charged electrons and positively charged protons.

Step-by-step explanation:

A neutral atom has the same number of protons and electrons. This is because negative and positive charges of equal magnitude cancel each other out, ensuring that the atom's overall charge is zero. Each proton, which has a positive charge, is counterbalanced by an electron, which has a negative charge. If an atom has 1 proton, it will have 1 electron; similarly, if it has 10 protons, it will have 10 electrons, and so on. The property that differentiates one element from another is its atomic number, which indicates the number of protons in the nucleus of an atom.

Additionally, the mutual attraction between the positively charged protons and negatively charged electrons grants the atom some structural stability. In this way, the number of protons and electrons within a neutral atom are equal, making the atom's overall charge balanced. However, it is worth noting that atomic weight and atomic number do not necessarily match because atomic weight also accounts for the mass of neutrons, which are electrically neutral. Nevertheless, an atom with an equal number of protons and electrons will be electrically neutral.

Step-by-step explanation:

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds.
