If a new element were discovered and it was found to form 1− ions, in which group would you place it in the periodic table?
2 answers:
Group 17 (or 7A, or VIIA): Halogens.
<h3>Further explanation</h3>This group contains the elements fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). These elements occur naturally in a diatomic structure
- Fluorine and chlorine are in the gaseous phase.
- Bromine is in the liquid phase.
- Iodine is in the solid phase.
- Astatine is a radioactive and solid element.
Halogens are the most highly reactive nonmetals. Therefore, they become negative one charged ions by gaining a single electron to complete their valence shell in the chemical reaction.
Thus, if a new element were discovered and it was found to form 1− ions, we would place it in the periodic table as a member of group 17, also known as group 7A or VIIA or halogens.
