which of the following is the correct valence dot model for fluorine, f?
which of the following is the correct valence dot model for fluorine, f?
Answer
Brief Explanations:
The provided Bohr model shows an atom with 9 protons (p+) and 10 neutrons (n0) in the nucleus. The number of protons determines the atomic number, which is 9, identifying the element as Fluorine (F). A neutral atom has an equal number of electrons and protons, so Fluorine has 9 electrons. These electrons are arranged in shells: 2 electrons in the first shell and 7 electrons in the second (outermost) shell. Valence electrons are those in the outermost shell. Therefore, Fluorine has 7 valence electrons. The valence dot model (Lewis dot structure) represents these valence electrons as dots around the element's symbol. For Fluorine (F), we place 7 dots around it, typically resulting in three pairs of electrons and one unpaired electron. Comparing this to the options provided, the first option correctly depicts Fluorine with 7 valence dots (three pairs and one single dot).
Answer:
The first option, showing F surrounded by 7 dots (three pairs and one single dot), is the correct valence dot model for Fluorine.
