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.
Sodium is a highly reactive soft greyish metal in its pure form, which is never found in nature because of said reactivity. Anyhow, to task: sodium has eleven (11) electrons, in a 2-8â1 configuration, with that one lonely valence electron in the outermost orbital/shell, accounting for the high degree of reactivity. In the nucleus are eleven (11) protons and twelve (12) neutrons. The only stable isotope of sodium is 24Na, which can only be formed thru nucleosynthesis at temperatures approaching 600 megakelvins.
