Periodic table help for chemistry?
1. why can period 1 contain a maximum of two elements? 2. in which period and group is the element whose electron configuration is [Kr[5s^1? 3. writethe outer electron configuration for the group 2 element in period 6. 4. what determines the number of elements found in each period in the periodic table? 5. are elements with similar chemical properties more likely to be found in the same period or in the same group? explain your answer. 6. how many calence electrons does phosphorus have? 7. what would you expect the electron configuration of element 113 would be? these are the only questions i don't know you don't have to answer them all Chemistry periodic table question?
Two elements are in the same column of the periodic table, one above the other. The ground state atom of one element has two s electrons in its outer shell, and no d electrons anywhere in its configuration. The other element has d electrons in its configuration. Identify the elements. Thank you!!Chemistry periodic table question?
So this is a bonus opportunity for Chemisty and id appreciate all the help i can get! -How many words can you make using the chemical symbols in the Periodic Table? You may use the symbols more than once in a word, but you cannot mix up the letters (i.e. the symbols must be used as they appear in the Periodic Table). Words should have at least 4 letters. You can use the names of people, places, and other elements. You must provide the symbols as well as the word. Examples: He At = Heat N O B O Dy = Nobody :Chemistry Periodic table and trends test practice?

A.) Ba B.)Sr C.Mg D.)Si 14.) a.) Fe, Al, pb b.) Mn, K, Zn c.) Ca, Ba, Ag d.) Na, P, MgChemistry: Barium- Using the periodic table how do I know the number of protons, neutrons, electrons, and mass?
I am brand new to Chemistry and in 101 and have a teacher who apparently believes in the self taught 'method' of learning. We have a test coming up and I am trying to teach myself everything on his review sheet for the test. Can someone tell me how I read a periodic table to know the answers to the questions posted. PLEASE Were just given the atomic number and he wants us to know the symbol, number of protons, number of neutrons, number of electrons, and the mass number. I am using atomic number 56 first which is Barium. We have to know alot of these and i'm not sure where to get the answers.
