Number of Protons + Number of Neutrons ATOMIC MASS / WEIGHTĦ NEUTRONS- I need to know the number of neutrons….ĭo you know the atomic mass / weight AND the number of protons? If so, subtract the number of protons from the atomic mass/ weight. Students then are asked to count the number of. Atomic structure worksheet - achieved Distinction Q5 - Write a list of questions about the costs of HE study and the possible sources of financial support that you should ask each university/college that you are considering for your HE studies. Students then count and add the number of neutrons to the proton total to ascertain the atomic mass. From there, students count the protons to determine the atomic number. Define mass number: Define atomic number: The three subatomic particles of the atom are: What are the relative masses of a. Do you know the number of protons and neutrons? If so, add the number of protons and neutrons to get the atomic mass / weight. The mystery atom has three different energy levels of electrons and students are directed to color each layer differently. Do you know the number of protons? If so, then they are the same number.ĥ ATOMIC MASS / WEIGHT- I need to know the atomic mass / weight…ĭo you have a periodic table of elements? If so, find the largest number (number with the greatest value) and round it to the nearest whole number, if necessary. Do you know the number of electrons? If so, then they are the same number.
Do you know the number of protons? If so, then they are the same number!Ĥ ATOMIC NUMBER- I need to know the atomic number….ĭo you have a periodic table of elements? If so, then find the number the periodic is organized by, and that is the atomic number. Do you know the number of electrons? If so, then they are the same number.ģ ELECTRONS- I need to know the number of electrons….ĭo you know the atomic number? If so, then they are the same number. Do you know the atomic number? If so, then they are the same number.
