When sodium reacts with chlorine to form an ionic compound, each metal atom loses _____ electron(s) and each nonmetal atom gains _____  electron(s).   There must be ___(1,2,3) sodium atom(s) for every ___ (1,2,3) chlorine atom(s) in the reaction.

Sharing Covalent bonding is explained as a bond that forms when atoms are electrons. When the two atoms get close enough, the nucleus of one atom weakly attracts the other atom's (Protons / Neutrons / Electrons ). When the two atoms get even closer, the nucleus of one atom has a strong attraction for both its_uclei and the electron from At this point both atoms are attracting ● You can see that the electrons spend almost all their time the two nuclei. When showing the attractions from another nucleus you can see that it is also pulling on both electrons. This is a bond. The atoms are both trying to one can take them away from the other. This creates a situation where both atoms are together. What region of the periodic table are their atoms that attract electrons strongly? Non Metals the same electrons, but neither H B
