By definition, an atom is electrically neutral (i.e. has the same number of protons as it does electrons, plus some number of neutrons depending on the isotope). If a species were charged, it is referred to as an ion (cation for positively charged and anion for negatively charged species), also by definition. Best Answer: 7 is neutral. Any number above 7, to a maximum of 14, means that the chemical is basic (a base). And any number below 7, to a maximum of 0, means the chemical is acidic (an acid). In a neutral atom the number of electrons is equal to the number of  protons. The opposite charge between protons and electrons is what  allows for a neutral atom. Now, in a neutral atom, the number of protons must be equal to the number of electrons, otherwise it would not be neutral. Basically, the definition is saying that in a neutral atom, the atomic number is equal to both the number of protons, and the number of electrons, because, well, they both are the same.. Compare this with an ion. A neutral atom is an atom where the charges of the electrons and the protons balance. Luckily, one electron has the same charge (with opposite sign) as a proton. Example: Carbon has 6 protons. The neutral Carbon atom has 6 electrons. The atomic number is 6 since there are Answered by The Community. Making the world better, one answer at a time. Neutral numbers or should I say number is a number that isn't prime nor composite and there is only one number that falls into that category. That number is 1, so 1 would be a neutral number.
