Question:

does valence electron and family number have the same value?

plsexplain why

Answer:

I just made boneless pork chops yesterday actually, first I made a rub which consisted of garlic powder, paprika, salt, onion powder, brown sugar, pepper and coated the chops then i seared them on the stove in an iron skillet on medium high until they were golden brown then i put them in the oven at 400 for 6-8 minutes, the whole thing took about 20 minutes and they were quite tasty!
I have a great pork chop recipe that doesn't take very long at all.a lot of people won't try it cuz it has sauerkraut involved but believe me.after it's done, the kraut doesn't taste like kraut anymore.it has the kraut twang but.you can try it if you want.it's incrediblePreheat your over to 350 Fry your pork chops until they're almost (but not quite done) In a baking pan, put the kraut on the bottom, lay the chops on top and keep layering it chops/kraut until you've used all the chopsOver the top of that.pour Cream of Mushroom soup and whole or sliced mushrooms and cover with foilBake for probably about 20 minutes.just till the chops are the rest of the way done and talk about delicious.
These is a good pork chop recipeIngredients 1 clove garlic 1/4 cup apple cider vinegar 2 tablespoons soy sauce 1/2 cup honey 1/4 teaspoon ground ginger 1 pinch ground black pepper 6 pork chops Directions 1.Place pork chops into a large resealable bagIn a blender or food processor, combine the garlic, vinegar, soy sauce, honey, ginger, and pepperPuree until the garlic has been finely choppedPour this mixture over the pork chopsSeal, and marinate in refrigerator at least 4 hours2.Preheat oven to 350 degrees F (175 degrees C)Transfer the pork chops and marinade to a baking dish3.Bake uncovered in the preheated oven until the sauce has reduced, and the pork is no longer pink in the center, about 25 minutes.
When looking at the periodic table, you can determine the number of valence electrons from the Roman numeral that precedes the A or B at the top of the columnFor example, aluminum is in group IIIA, and so aluminum has three valence electronsChlorine is in group VIIA, and chlorine has seven valence electronsZinc in in group IIB and has two valence electronsThis works for all for the groups except for group VIII, Fe, Co and Ni families Follow up For me and my students, who are not in Europe, there is no confusion with the A and B notationIt makes perfect sense and has for decadesThe A-column elements are the representative elements and the B-column elements are the transition metalsGroup VIII (Fe, Co, and Ni) doesn't give the number of valence electrons but neither does 8, 9 or 10The impetus for the 1-18 revision by the IUPAC was one of compromise, and like many compromises, it lost some of the usefulness of the system it replacedThis is why, at my behest, the periodic table that is part of the reference package for the end-of-course test in North Carolina has both the 1-18 labeling as well as the A and B labeling(I was part of the committee that developed the NC state chemistry curriculum in 1998 and 2003.) For groups 1-11 (Cu group) the group number indicates the number of valence e?Does this imply that copper has eleven valence electrons? If the valence electrons are those that are involved in reactions, then you cannot say that copper realistically has 11 valence electronsNot all of the electrons in the 4s and 3d are going to be involved in reactionsAnd the same is true for Fe, Co, and NiFor all practical purposes, the number of valence electrons tops out about 6 for metals and certainly no more than 8.
