Now we need to find the mass number of argon. The elements on the periodic table are organized by. Web all atoms of the same element have the same number of protons, but some may have different numbers of neutrons. Group 17, because it has 17 valence electrons in each. Web 18 , and the element with atomic number 18 is argon with the symbol a r. Number of electrons = 11. Web isotopes are simply specifying the number of neutrons and protons (together called nucleons) in the atom. Because m ass number − atomic number = n o of. Web calculate the number of protons, neutrons and electrons it contains. Group 2, because all the elements in it are metals.
Number of electrons = 11. Now we need to find the mass number of argon. Web isotopes are simply specifying the number of neutrons and protons (together called nucleons) in the atom. Web actually, 18 is argon's atomic number, and it also has 18 protons and electrons. Web and the element with atomic no. Web calculate the number of protons, neutrons and electrons it contains. For example, all carbon atoms have six. The required element is argon and. Group 2, because all the elements in it are metals. Group 17, because it has 17 valence electrons in each. Now we need to find the mass number of argon.
