Question

the group 17/vii elements are known as the halogens. answer the following true or false questions about them. all are nonmetals 1 they like to gain 1 electron 2 they like to form anions 3 when they gain the electron they are attracted to cations 4 a. true b. false

Explanation:

1. Halogens (Group 17 elements) such as fluorine, chlorine, bromine, iodine, and astatine are all non - metals.
2. They have 7 valence electrons and need to gain 1 electron to achieve a stable octet configuration.
3. By gaining an electron, they form negatively - charged ions (anions).
4. Cations are positively - charged ions, and anions are attracted to cations due to electrostatic forces.

Answer:

1. A. true
2. A. true
3. A. true
4. A. true
