atom and identify where each type of subatomic particle
would be located.

Guys first, an ionization, energy and metallic character. And then to have each member present his inner table to the right of the group and explain the trend based on the concepts such as the size or effective nuclear charge. So we only have one person. So I'm gonna do all of those trends. I'm gonna do them on the same periodic T. We're gonna pretend that these lines are straight. We're not from includes the F block in this analysis, anything that the train is gonna proceed in the same unit. The first concert we're gonna look at his atomic size. We're going to atomic size and red as you go across table. From left to right, the atomic size decreases, so I'm gonna write the word decrease. All right, so we go from left to right, the atomic size decreases, and as we go down, the periodic table of the atomic size increases. We're gonna look at this based on the concept of effective nuclear charge. As you go across the table, effective nuclear charge increases. So the protons in the center have a more positive charge. The electrons on the outside are therefore so if they're all in the same energy level, more attracted to that net positive charge, causing that greater attraction. This side of the atoms would be smaller. But as you go down, yes, the effective nuclear charge increases. But there's additional outer orbit or outer energy level, so that makes the, uh the size of the atom increase every time you go down a group on the periodic table. So as you go across the decreases and as you go down, it increases. Now let's d'oh! First ionization energy and green. You're looking at first ionization energy your F i E. As we go across the periodic table, it's going to increase. And as you go down the periodic table, the first ionization energy is actually going to decrease. Now, let's explain why again, using effective nuclear charge first, I'm relation. Energy is the energy to remove an electron, and if we think about this similarly in terms of effective nuclear charge, d'oh greater the effective nuclear charges. A greater the electrons and the energy level feel that positive charge, the more energy is going to take to remove it. So as we increase the effective nuclear charge going across the periodic table is described previously, it takes more energy to remove an electron and therefore the energy to ionized. That increases again as you go down the periodic table we've discussed. The effective nuclear charge of the nucleus, of course, gets larger, but because it's an outer energy level, it's not as another out of energy level As we go down each group as we go down the group, it doesn't take much energy to remove that electron and therefore decreases as we go down. And lastly, we're looking at metallic can't Jim. We're gonna do this in blue emcee for metallic character. As we go across the periodic table of the macaca, metallic character decreases. And as we go down periodic table, the metallic character increases so as you can. As you see, the trend for my talent character is similar to that for atomic size. The reason why metallic character decreases as we go across the periodic table is because my stomach Adam, the things that make up metallic character include the ability to conduct electricity, be malleable, be duck towel and also have things that lose electrons. So those air cat ons, cattleman's lose electrons. We know that Kat on is it mostly located on the left side, the periodic table as opposed and ions in the rights of periodic table. So macaca character's gonna be more towards left side of the table than the right and decreases the girl across as it relates to effective nuclear charge, or is as something as a cat on is willing to lose that electron. What's easier because of the effective nuclear charge is not as great. And therefore it's has more likely to have a COT character versus something over here that has a stronger, effective movie a charge and is less likely to lose that electron again considered effective nuclear charge. The metallic character decreases are increases. Excuse me as we go down a group because it is easier for something behavior kept on and lose that electron because it doesn't feel the effects of nuclear charge further on the bottom of the periodic table. That's something that's close to the top. So these trends that are related to the fact that over here from the left side, the periodic table is a left side of direct table has a smaller, effective nuclear charge, and then it increases would go down. And unless I've narrative, was it smaller? Effective Earth decreases. Excuse Miss West. Let's write this as you go down the periodic table. You're effective. Nuclear charge. What we're gonna do know as E he said, this decreases as you go across the periodic table effectiveness. The charge is going to increase, and all of these trends are related to that.

Yeah, that was made up with protons and neutrons on the inside. This is where the massive madam outside of the center of the Adam are the electrons which rotate over the Adam and hold the church.

King here, three different types of radiation health beat up in camera. Both beta and Gamma general changed the mass number nor the atomic number. But Alfredo's and L for creation Two electrons in two protons are released. Therefore, the mass number is reduced by four as for removed as well as atomic mass duties to pay for.

So now we'll work on problem 90 from Chapter five This problem where has to draw several electron dot structures. Four's a few elements. So the 1st 1 which were given his carbon carbon eyes represented by the letter C and we need to know how many ballots electrons Theo have. So we look for carbon and we see that has four valence electrons, so it should have an electron each side. Bits for part B were asked for the electron dot structure for our snack. So arsenic is represented by A s in arsenic has five valence electrons. So her snake we will have one electron on three sides and two electrons on one side. For part c, we now have polonium. Now polonium is represented by P O and polonium has six bills Electrons so two sides will have two electrons and one side will have won election in Part D were asked to drop a stretcher for potassium. Potassium, of course, is represented by the letter K and it has only one balance electrons. So we only have one dot there and finally and party were asked for the electron about structure for barium, which is represented by A and barium has to surveillance electrons. So we only draw two dots next
