Mass number 9 of 31 How do we find out the number of protons Proton Number 10 of 31 How do we find out the number of electrons Proton number 11 of 31 How do we find out the number of neutrons mass number-proton number 12 of 31 What is the number of neutrons of an element with a mass of 7 and 3 protons 4 (7-3) 13 of 31 Which two sub atomic particles are ALWAYS the same Protons and electrons 14 of 31 What are Isotopes Atoms of the same element with different mass numbers. The same number of protons but different numbers of neutrons. 15 of 31 what is the relative atomic mass mean average mass of the atoms. 16 of 31 How many electrons can the first shell hold 2 17 of 31 How many electrons can the second shell hold 8 18 of 31 How many electrons can the third shell hold 8 19 of 31 In an electron arrangement off 2.8.8, are the shells full yes 20 of 31 What does the last number in an electron arrangement stand for. Group Number 21 of 31 What does the number of shells in an electron arrangement stand for. Period Number 22 of 31 On a periodic table is the group number along the top or down the side Along the top 23 of 31 What group number is an element with an electronic configuration of 2.4 in 2.4 24 of 31 What period is an elemen with an electronic configuration of 2.8.5 3 25 of 31 What are the ways in which Isotopes of the same element are the same. Same number of protons and electrons. 26 of 31 Isotopes of the same element have a different ......... number mass 27 of 31 What does r.a.m stand for relative atomic mass 28 of 31 Why must the mass number be a whole number mass of a single atom, not an average. 29 of 31 What is the formula to find the r.a.m (n.o x mass) + (n.o x mass)/ total number=r.a.m (it's all divided by the total. If it was a percentage it would be 100 30 of 31 If 6 atoms had the mass of 35 and 2 had a mas of 37, whats the r.am (6 x 35) + (2 x 37)/ 8 = 71/2=35.5 31 of 31
