To determine: The number of electrons in a fluorine atom.
Concept introduction: The atomic number of an element is the number of protons in the nucleus of its atoms. In a neutral atom, the number of protons and electrons is equal. Thus, the number of electrons present in a neutral atom is equal to its atomic number.
To determine: The number of shells in a fluorine atom.
Concept introduction: The electrons in an atom present around the nucleus are in constant motion. An electronic shell represents the energy levels and the average distance at which electrons orbit around the nucleus. Simplified diagrams of atoms show the electrons arranged in electronic shells as concentric rings around the nucleus. In an atom, the first shell can contain only two electrons, whereas the second shell can have a total of 8 electrons.
To list: The names of orbitals occupied by electrons in a fluorine atom.
Concept introduction: Electronic shells can be subdivided into electronic orbitals. Each electronic orbital represents the three-dimensional volume around the nucleus where an electron is most likely to occur while orbiting around the nucleus. Each orbital can have two electrons. Thus, the number of electrons present in each shell depends on the number of orbitals in each shell. In an atom, the first shell has one orbital called 1s, thus it can contain only two electrons. The second shell has one spherical orbital called 2s, and three dumbbell shaped orbitals named 2p orbitals (Fig. 2). Thus, the second shell can have a total of 8 electrons.
To determine: The number of electrons needed to completely fill the valence shell of a fluorine atom.
Concept introduction: The outermost shell of an atom is called the valence shell, and the electrons present in it are called valence electrons.

- If someone was working with a 50 MBq F-18 source, what would be the internal and external dose consequences?arrow_forwardWe will be starting a group project next week where you and your group will research and ultimately present on a current research article related to the biology of a pathogen that infects humans. The article could be about the pathogen itself, the disease process related to the pathogen, the immune response to the pathogen, vaccines or treatments that affect the pathogen, or other biology-related study about the pathogen. I recommend that you choose a pathogen that is currently interesting to researchers, so that you will be able to find plenty of articles about it. Avoid choosing a historical disease that no longer circulates. List 3 possible pathogens or diseases that you might want to do for your group project.arrow_forwardnot use ai pleasearrow_forward

In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardIf a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forward
