Question

boxes below are labeled with the approximate atomic masses of four different elements Using the provided atomic masses and the periodic table shown, drag the appropriate subatomic particle the boxes to create electrically neutral atoms. Once you've created your atom, drag the atoms symbol into the box as well. 40 neutrors 32 clectrons He Kr 10 i BeB 2 electrons4 protons 36 protons 32 protons 2 protonsGe neutrons 4 electrons 69, 9012| 1O 81 1201 1401 1600 | 1900| 2018 11 12 13 14 15 161718 36 electrons Be 99 | 2431 | 2698 | 28, 3097 | 3207 | 3545 | ??6 19 20 31 3233436 36 48 neutrons 5 neutrons neutrons 3910 40.08 60.7272.59 74.92 78.96 79.90 83 60 Atomic mass Atomic mass 84 Atomic mass4 Atomic mass 72

Explanation / Answer

Atomic no. = Proton no. (We can know it from the above no. of particular atom symbol in periodic table)

When electrically neutral, Proton no. = Electron no.

Neutron no. = Atomic mass - Atomic no. = Atomic mass - Proton no.

Atomic Mass No. of electrons No. of protons No. of neutrons Symbol 9 4 4 5 Be 84 36 36 48 Kr 4 2 2 2 He 72 32 32 40 Ge
