Any atom of Calcium can have 20, 22, or 24 neutrons. These different versions of Calcium are called 1. Any atom of Calcium can have 20, 22, or 24 neutrons. These different versions of Calcium are called ____________________. ____________________. 2. 1 Calcium atom has 22 neutrons and another Calcium atom has 24 neutrons. Why are these both Calcium atoms even though they have a different # of neutrons? 2. 1 Calcium atom has 22 neutrons and another Calcium atom has 24 neutrons. Why are these both Calcium atoms even though they have a different # of neutrons? 3. Which element in the above table has 2 Isotopes? How are you sure? 3. Which element in the above table has 2 Isotopes? How are you sure? 4. Which element above is an ION? How are you sure? 4. Which element above is an ION? How are you sure? Neutral, Isotope and Ion Neutral, Isotope and Ion Choose any element with an atomic number of less than 20. Inside the circle (nucleus), draw the number of protons and neutrons in Choose any element with an atomic number of less than 20. Inside the circle (nucleus), draw the number of protons and neutrons in one atom of that element. Use + for protons and 0 for neutrons one atom of that element. Use + for protons and 0 for neutrons Draw electrons outside the circle. Use – for electrons. Draw electrons outside the circle. Use – for electrons. Neutral Atom of __________________ Neutral Atom of __________________ Isotope of _________________ Isotope of _________________ Ion of ____________________ Ion of ____________________ Why are these all atoms of the same element? Why are these all atoms of the same element?
