1) how can you determine the number of protons in the nucleus of an atom of any of the elements listed in the table? 2) which element has 14 protons in the nuclei of its atoms? 3) explain how you can determine the number of electrons surrounding the nucleus of an atom of any of the elements listed in the table.4) which element has 19 electrons surrounding the nuclei of its atoms? 5) explain how you can determine the number of neutrons in the nucleus of an atom of any of the elements listed in the table.6) which element doesn’t have a neutron in the nuclei of its atoms? 7) how many neutrons are present in the nucleus of an iron atom? 8) how many protons, neutrons, and electrons are present in and surrounding the nucleus of a chlorine atom?

This is about understanding atomic and mass numbers of elements.

All the answers are explained below;

1) When we look at the periodic table, we see that each element has a number written at the top left corner of its' box. This number denotes the atomic number which is equal to the number of protons in the nucleus of the atom of that particular element. 2) From 1 above, the atomic number is the same as number of protons. Looking at the periodic table, the element with Atomic number of 14 is Silicon (Si). 3) In chemistry, it is well known that the number of electrons surrounding the nucleus of an element's atom is equal to the number of protons inside the nucleus of the atom. Thus, the number of electrons is equal to the number written at the top left corner of the box housing the element. 4) From the periodic table, the only element with atomic number of 19 is Potassium (K). 5) The number of neutrons of any element is gotten by subtracting its' atomic number from its' atomic weight. In some periodic tables, this atomic weight is usually written at the bottom left of the element. 6) The only element that doesn't have neutrons is Hydrogen (H). This is because its' atomic weight and atomic number are both 1. Thus, the difference which gives number of neutrons is zero. 7) Iron has an atomic number of 26 and an atomic weight of 56. Thus

Number of neutrons in iron = 56 - 26 = 30 neutrons.

8) From the periodic table, chlorine has an atomic number of 17 and an atomic weight of 35. Thus, it will have 17 protons and 17 electrons.

Number of neutrons = 35 - 17 = 18 neutrons
