Hey, one general terms. How does each of the following atomic properties influence the metallic character of the main group? Elements in a period, Um, a ionization energy be atomic radius. See the number of outer electrons and d effective nuclear charge. So I have given you a picture of the periodic table on your board, and I've also put the periodic trends of each of those 8 30 questions. So in the top right corner, we have the highest ionization energy, the most number of outer electrons, also known as valence electrons and the highest F effective nuclear charge. And then in the bottom left corner, we have the largest atomic radius. It's worth mentioning that, um, the left side of the periodic table up until about. Here is where we have our medals on our periodic table and then on the right side in the corner is where we have our non metals located. So that should give you a hint that ionization energy having a high ionization energy number of outer electrons and effective nuclear charge is inversely related to metallic properties. But we should talk about each of them specifically, let's begin with effective nuclear charge though, because I think that's the most important out of all of these. So effective nuclear charge is a measure of how strong the attraction is between the outer valence electrons and the protons that are located in your atoms nucleus. So if you remember the structure of an atom in our nucleus, we have these positively charged protons and then in our orbital surrounding the nucleus is where we have our electrons of effective nuclear charge is a measure of how strong these electrons are attracted to our inner protons. Remember, opposite charges attract. So if we have the highest effective nuclear charge here, meaning they are most closely bonded, um, to our inside, that means that we're less likely to give up those valence electrons which decreases our metallic character. Remember, metals can easily trade electrons amongst each other. That's one of the principles of conductivity. Um, and then ionization energy again is a measure of how easily we can give up electron, so that is directly telling us how metallic our substance is. All of these answer choice is kind of all feeding together because, you know, if we have a high number of outer electrons, that means we have more negative charge in our outside nucleus, which means we also have more positive charge. Uhm, in our nucleus, which again all of these kind of go hand in hand they are directly related to our metallic character.
