In fact, there are several diseases that can be transmitted to your pet from a tick bite. Some of the most common tick-borne diseases seen in the United States are Lyme disease, Rocky Mountain spotted fever, ehrlichiosis, and tick paralysis. Here we will briefly discuss these and some of other tick-borne diseases that affect dogs and cats.
The inner transition metals are shown in two rows at the bottom, in pink and purple. An inner transition metal is one of a group of chemical elements on the periodic table. They are normally shown in two rows below all of the other elements. They include elements 57-71 (lanthanides) and 89-103 (actinides). The lanthanides are very similar, and the actinides are all radioactive. They have three incomplete outermost electron shells and are all metals.
The transition metals are found in groups 3 through 12. You may notice that we are leaving out that 'island' of elements down below. The top row of that island makes up the lanthanides and the bottom row makes up the actinides. We are leaving these out because they are neither main group elements nor transition metals. Main Group Elements. The main group elements are by far the most abundant elements - not only on Earth, but in the entire universe. For this reason, they are sometimes called the 'representative elements.' The main group elements are found in the s- and p-blocks, meaning that their electron configurations are going to end in s or p. Remember the s- and p-blocks are responsible for providing the valence electrons, those super-important electrons that are involved in chemical bonding. Both the electron configurations and the number of valence electrons are very predictable as we move across the main group elements. Group 1 has elements with one valence electron, group 2 has elements with two, group 13 has elements with three valence electrons and so on to group 18, with eight valence electrons.
