The lining of the esophagus is an example of a non-keratinized or moist stratified epithelium. Transitional. Transitional epithelia are found in tissues that stretch and it can appear to be stratified cuboidal when the tissue is not stretched or stratified squamous when the organ is distended and the tissue stretches.pithelium lines both the outside (skin) and the inside cavities and lumina of bodies. The outermost layer of human skin is composed of dead stratified squamous, keratinized epithelial cells.
Answers. Best Answer: For an alkali metal such as sodium, lithium, or potassium, there is only a single valence electron. In terms of electron orbitals, you would have 1s^2 ... n s^1, where n is any integer greater than one.
And since all elements with, lets say 2 valence electrons, all go into the same group, and since valence electrons greatly affect chemical properties, elements are grouped by their chemical properties/number of valence electrons. the closer an element is to 0 or 8 valence electrons the more reactive it is.
