- Some questions frequently asked by houseowners : need for classification of elements in a periodic table.?
♥ hello friends. i am writing a seminar on "need for classification of elements in a periodic table". please help me. i could not find anything on google. please give me the advantages also. give me information on dobrenier's table, newland's table and mendeleeve's table. also please explain me about the modern periodic tables of mosley and others please explain me about the history of periodic table. give me lots of information so that i can write it in the seminar paper. please give me maximum information. more and more helps me more and more in the seminar. i need at least 5 to 7 pages. please don't give me 2 to 3 lines information. if you could not writ it here then please give me the link where can find the information. please i want it within 1st of june. thanks for all who help me.explain the classification of the periodic table in terms of s,p,d,f blocks?
♥ please can you show examples. i am really confused on this question. thanks for all the help.are transition metals and transition elements the same ?
♥ and um what are they ? what is their specialty and properties ?and examples ? and classification ? and don't tell me to read it in wikipedia because i already did . please help ?chemistry - i need help with the classification of elements quiz - 10 questions only.?
♥ here are the questions that i've come across that i've been rather quizzical about. hopefully i can get some help on the subject matter at hand. 1.)compounds like nacl and h2o are made up of: a.)random numbers of the atoms that make up nacl and h2o b.)definite proportions of the elements na, cl, h, and o c.)definite proportions of the compounds nacl and h2o 2.)all atoms of the same element have the same number of: a.)protons b.)neutrons c.)electrons 3.)use the periodic table to answer the following question. every known substance is made of one or more of the 112 elements found on the periodic table. a.)true b.)false 4.)use the periodic table to answer the following question. carbon, silicon, oxygen, iron, calcium, nitrogen, tin, and neon are all examples of elements. a.)true b.)false 5.)gaining neutrons makes an element: a.)more positive in electrical charge b.)more negative in electrical charge c.)have no change in electrical charge 6.)if an element loses one electron and gains two neutrons, then it is considered a.)an ion b.)an isotope c.)both an ion and an isotope 7.) use the periodic table to answer the following question. across the periodic table, each succeeding element in the same period (row) has increased a.)atomic size, electronegativity, protons b.)electronegativity, ionization energy, protons c.)atomic size, protons, ionization energy 8.) use the periodic table to answer the following question. silicon has a larger ____________________ than carbon. answer a.)atomic size b.)electronegativity c.)ionization energy 9.) use the periodic table to answer the following question. compared with group 2 elements, group 14 elements have answer a.)less electronegativity b.)more valence electrons c.)more isotopes 10.) use the periodic table to answer the following question. which of the following elements holds its electrons with the most energy? answer a.)lithium (li) b.)beryllium (be) c.)boron (b) well, those are all of the questions that i need help with. i'd be grateful if most of those were answered. these questions are not only going to help me with school, but it'll help secure a future because a degree is needed regardless where you go in life. thank you to those who read these questions and those who were able to answer them. i'd love it if these were answered as soon as possible. anyways, take care everyone and have a good day. 1-b - correct 2-a - correct 3-a - correct 4-a - correct 5-b - incorrect 6-c - correct 7-a - incorrect 8-a 9-b - correct 10-a - incorrect thank you for your help; it's much appreciated. if anyone knows the rest of the answers to the questions, it'd be much appreciated. thank you for your time and thank you to those who may help and have already helped. have a good day and take care. -linette oh, and 8-a was correct as well.best way to approach learning periodic table?
♥ i am an adult but i dropped out of high school and had no science at all. although i am in a community college now, they more or less expect me to already know this stuff even if it is an "intro to chemistry" type class. i have the internet and apps but i am a bit overwhelmed here. just how much should i know? i have everything from "binding energies", "electrogravity", "classification", "period" "she'll structure" and density. that is along with the usuals like classification and atomic number. just how much of the information of each element to i need to be successful in an intro to college class? i'm also learning for self knowledge. i really want to know what sulfer (for example) is and how it reacts with __ element also. i want to instantly know these things for my own fulfillment. what is a good method.
