whoch statement best describes the arranement of electrons in an atom of flurine F

1 answer

The arrangement of electrons in an atom of fluorine (F) can be described as follows:

Fluorine has an atomic number of 9, which means it has 9 electrons. These electrons are arranged in the following way:

  • The first energy level (closest to the nucleus) contains 2 electrons.
  • The second energy level contains the remaining 7 electrons.

This can be expressed using the electron configuration notation as:

\[ 1s^2 , 2s^2 , 2p^5 \]

In summary, the best statement to describe the arrangement of electrons in a fluorine atom is that it has 2 electrons in the first energy level and 7 electrons in the second energy level, making it a highly electronegative element with a tendency to gain one more electron to achieve a stable octet configuration.
