Some questions frequently asked by users : atomic structure worksheet easy. (10 points here!!!!!)?
okay, so it's my summer worksheet but my teacher told me that i can look the answers but i lost the answer worksheet! so, im doing this worksheet and im done, i want you to tell me the answers because i want to make sure it's corrects! 10 points!!! thanks :d 1.the 3 particles of the atom are: a.______________________ b.______________________ c.______________________ their respective charges are: a.______________________ b.______________________ c.______________________ 2.the number of protons in one atom of an element determines the atom’s ______________________,and the number of electrons determines ______________________of and element. 3.the atomic number tells you the number of ______________________in one atom of an element. it also tells you the number of _____________________in a neutral atom of that element. the atomic number gives the “identity “ of an element as well as its location on the periodic table. no two different elements will have the _____________ atomic number. 4.the ______________________of an element is the average mass of an element ’s naturally occurring atom, or isotopes, taking into account the ______________________of each isotope. 5.the ______________________of an element is the total number of protons and neutrons in the______________________ of the atom. 6.the mass number is used to calculate the number of ______________________in one atom of an element. in order to calculate the number of neutrons you must subtract the ___________________from the ______________________. 7.give the symbol and number of protons in one atom of: lithium __________________ bromine __________________ iron __________________ copper __________________ oxygen __________________ mercury __________________ krypton __________________helium _____________________ 8.give the symbol and number of electrons in a neutral atom of: uranium __________________ chlorine __________________ boron __________________ iodine __________________ antimony __________________xenon __________________ 9.give the symbol and number of neutrons in one atom of: (to get “mass number ”,you must round the “atomic mass ” to the nearest whole number)) show your calculations. barium __________________bismuth __________________ carbon __________________hydrogen __________________ fluorine __________________magnesium __________________ europium __________________mercury __________________ 10.name the element which has the following numbers of particles: a.26 electrons,29 neutrons,26 protons _____________________ b.53 protons,74 neutrons _____________________ c.2 electrons (neutral atoms)_____________________ d.20 protons _____________________ e.86 electrons,125 neutrons,82 protons (charged atom ____________________ f.0 neutrons _____________________ 11 .if you know only the following information can you always determine what the element is? (yes/no). a. number of protons ___________ b.number of neutrons___________ c.number of electrons in a neutral atom___________ d.number of electrons___________chemistry atomic structure help?
i need help on a worksheet i need to fill in the spaces. please help 1. the atomic number tells you the number of ________ in one atom of an element. it also tells you the number of ________ in a neutral atom of that element . the atomic number gives you :identity" of an element as well as its location in the periodic table no two different elements will have the ______ atomic number. 5. the mass number of an element is the total number of protons and neutrons in the _____of an atom. 8. give the symbol and number of electrons in a neutral atom: uranium______ chlorine________ boron____ iodine___________ 10. name the element which has the following number of particles/. 1. 53 protons, 74 neutrons ________ 2. 2 electrons(neutral atoms) __________ 3. 20 protons ___________ 4. 86 electrons, 125 neutrons, 82 protons ________ 5. 0 neutrons ___________ please if you know just copy and paste this with the answers. 10 ponits! thanksneed help in biology and chemistry?
1)describe what happens to the size of an object when you look at it under lowest power lens and highest power lens of a microscope? 2)which objective lens magnifies the object the most? 3) which objective lens magnifies the object the least? 4)describe what happens to the position of the object (a penny) when you look at it under the microscope. 5) what is the difference between atom and element? 6) what elements are represented by the chemial symbols c,h,o,n,s,p,na,k,cl,ca,fe,mg,cu,b? 7)how do electron shells relate to atomic structure?help if your any good at chemistry?
help if your any good at chemistry? ok so im so stuck on chemistry like all those words im just like what so we got this worksheet and it was to highlight like all the thinks you know and dontknow and i didnt i have one full page green i got 3 boxes green and the rest i dont have a clue so please help iidentifythe following families of elements : - the halogens -the alkali metals - the noble gasses what does this mean ? q2)how can you describe an atom as having a very small ppositivelycharged nucleus with negatively charged electrons moving around outside the nucleus q3) how can i describe the location & charge of the proton & neutron& electron please answer this ill appreciate i.
