Answer :
To determine which element would most likely have chemical properties similar to that of fluorine (F), we need to consider the periodic table's structure. Elements that are in the same group (vertical columns) typically have similar chemical properties because they have the same number of electrons in their outermost shell, which dictates their chemical behavior.
Fluorine is in group 17 of the periodic table, which is more commonly known as the halogens. The halogens are known for being very reactive nonmetals. Let's examine the given choices to see which one belongs to the same group as fluorine:
1. Ne (Neon) - Neon is a noble gas, not a halogen. It's located in group 18, which is adjacent to the halogens but has a full valence shell, making these elements typically nonreactive.
2. N (Nitrogen) - Nitrogen is also not a halogen. It is in group 15 and does not share similar chemical properties with fluorine. Nitrogen is part of the nitrogen family or pnictogens.
3. Z - This is not a valid chemical element symbol, so we can dismiss it.
4. Li (Lithium) - Lithium is an alkali metal found in group 1 of the periodic table. Alkali metals are very reactive like halogens but have very different chemical properties because they tend to lose an electron, whereas halogens typically gain an electron during chemical reactions.
5. Br (Bromine) - Bromine is the element that belongs to the same group as fluorine, group 17, the halogens. Bromine and fluorine both have seven electrons in their outermost shell, making their chemical properties similar. For example, both elements can form negative ions by gaining an electron.
Therefore, the element that would have the most similar chemical properties to fluorine is Bromine (Br).
