1...Draw an atomic model of the following elements. You may draw your image by hand, using Microsoft Paint or the draw function in PowerPoint :Carbon ,Hydrogen ,Oxygen ,Nitrogen. 2...Include the following for each: protons, neutrons and electrons. 3..For each element: Write tree to four sentences describing the relationship between the total # of electrons, the # of valence electrons, and # of chemical bonds the atom tends to form.

please answer this question correctly.   1. What is the difference in the electron configuration for the magnesium  atom and the ion?

Which of these elements would be predicted to form an anion when ionized? a.) sodium b.) barium  c.) oxygen d.) aluminum

What is the electron configuration for aluminum? type your answer... Copy and paste the valence into this box: type your answer... This contains how many valence' electrons: type your answer... Aluminum will become a(n) choose your answer... > which means it choose your answer... Which Noble gas will aluminum want to become like(use the symbol)? type your answer... What is the electron configuration for this Noble gas? type your answer... Knowing how many valence electrons Al has, and how to tell which type of ion an element will become, adjust Al's electron configuration and place Al's ion electron configuration in the box. type your answer... What do you notice about these two configurations (choose the best answer) choose your answer... <
