Explanation:

To determine what makes an atom neutral, we analyze the table. For Hydrogen: protons = 1, electrons = 0 (but charge is +1, not neutral). Wait, no—wait, Carbon: protons = 6, electrons = 6, charge = 0. Lithium: protons = 3, electrons = 4, charge = -1 (not neutral). Wait, maybe I misread Hydrogen. Wait, Hydrogen: protons 1, electrons 0? No, maybe a typo, but Carbon: protons 6, electrons 6, charge 0. So when number of protons (positive charge) equals number of electrons (negative charge), their charges cancel (since proton charge is +1, electron is -1). So for an atom to be neutral, the number of protons must equal the number of electrons. We checked the table: Carbon has 6 protons and 6 electrons, charge 0. Lithium has 3 protons, 4 electrons, charge -1. Hydrogen (maybe a typo, but Carbon is clear). So by comparing proton and electron counts with charge, we see equal protons and electrons give neutral charge.

Answer:

For an atom to be neutral (overall charge of zero), the number of protons (positively charged particles) must equal the number of electrons (negatively charged particles). This is because protons have a charge of \( +1 \) and electrons have a charge of \( -1 \); when their quantities are equal, the positive and negative charges cancel out. To determine this, we analyzed the table: for Carbon, the number of protons (\( 6 \)) equals the number of electrons (\( 6 \)), and its charge is \( 0 \). For Lithium, protons (\( 3 \)) ≠ electrons (\( 4 \)), and its charge is \( -1 \). For Hydrogen (despite a possible typo in electron count, the pattern from Carbon holds), equal proton and electron counts correlate with a neutral charge.
