Question

incorrect. the chemical symbol is wrong. an atomic cation with a charge of + 1 has the following electron configuration: he 2s²2p⁵. what is the chemical symbol for the ion?

Explanation:

Step1: Determine the number of electrons in the ion

The electron - configuration [He]2s²2p⁵ indicates that the number of electrons in the ion is 2 (from [He])+2 (from 2s²)+5 (from 2p⁵)=9 electrons.

Step2: Determine the number of electrons in the neutral atom

Since the ion is a cation with a charge of + 1, the neutral atom has one more electron than the ion. So the neutral atom has 9 + 1=10 electrons.

Step3: Identify the element

The number of electrons in a neutral atom is equal to its atomic number. An element with an atomic number of 10 is neon (Ne), but we are dealing with a + 1 cation. The element with an atomic number of 9 is fluorine (F). When fluorine loses one electron, it forms a F⁺ ion.

Answer:

F⁺
