How do valence electrons determine chemical reactivity?

WebThe way elements react with each other is determined by the number of electrons in their outermost shells. Why do isotopes of the same element behave the same way in chemical reactions? Isotopes have the same number of electrons What is the difference between a compound and an element? WebFor example, as you move across a period, atoms have more protons in the nucleus, which pulls the electrons in tighter making smaller, more electronegative atoms. As you proceed down a column of the periodic table, the valence electrons get further away, and the atoms get larger and less electronegative. bmr assignment 4 answers

WebThe TEM has allowed us to see individual atoms and structure of cell nuclei. The scanning electron microscope (SEM) provides images by using secondary electrons produced by the primary beam interacting with the surface of the sample (see Figure 2). The SEM also uses magnetic lenses to focus the beam onto the sample.
