Wright the electron dot notation for all the elements in the following columns of the periodic table (see pp. 116-17) A column 2 B column 15
what generalization seems to be true about the electron dot notation for elements in a column of the periodic table

Which of the following statements is true about energy quantization at the atomic level? electrons in the outermost orbits are the most stable. electrons in all the orbits around the nucleus have the same amount of energy. electrons in the orbit closest to the nucleus have the least amount of energy. electrons absorb or release the same amount of energy independent of the energy levels.

If you are told to get 100 ml of stock solution to use to prepare smaller size sample for an experiment, which piece of glassware would you use?

Identify the limiting reactant when 9.65-g h2so4 reacts with 6.10-g of naoh.the equation is h2s04 + 2naoh = 2h2o + na2so4• what is the theoretical yield of na2so4, in grams? • how much of the excess reagent will remain after the reaction has been completed? • if 10.5-g of na2so4 are actually recovered experimentally, what is the percent yield?
