Atoms And Ions Worksheet The total atomic mass of a helium atom is 4 0026amu Using the data from the table we see that the mass of electrons in the atom is 0 0010972amu while the mass of protons is 2 015amu Therefore electrons take up 0 0274 of the mass of the atom while protons take up 50 342
Unit electrical charge is 1 6022 times 10 19 coulomb C The nucleus at the center of the atom contains one or more positively charged protons All atoms of a given element have the same number of protons which defines the element s atomic number given the symbol Z In addition the nucleus may contain one or more neutrons which have approximately the same mass as protons but Worksheet 1A Atoms Ions and Naming Compounds Page ID 1 Fill in the following table 2 Fill in the following table 3 Predict the charge of the most stable ion of each atom Mg M g Al A l K K S S F F Sr S r Sc S c P P I I Se S e 4 Predict the chemical formula and name for the ionic compound formed by the following Ca C a and Br B r

Atoms can gain or lose electrons to become ions Ions are charged atoms resulting from the difference in number of positive protons and negative electrons A cation is a positive ion A cation results when an atom loses electrons Protons Electrons An anion is a negative ion An anion results when an atom gains electrons Atoms and ions MahaShalash Member for 1 year 7 months Age 12 14 Level grade 7 Language English en ID 1925059 08 03 2022 Country code QA Country Qatar School subject Science 1061951 Main content Atoms and ions 1725025 electronic configuration of atom and ion Other contents electrons and protons Share Print Worksheet Finish
