Answer 2

The electron configurations for atoms with 9, 11, and 19 electrons are as follows:

1. Atom with 9 electrons: The element with 9 electrons is fluorine (F).

Electron configuration of fluorine: 1s^2 2s^2 2p^5

2. Atom with 11 electrons: The element with 11 electrons is sodium (Na).

Electron configuration of sodium: 1s^2 2s^2 2p^6 3s^1

3. Atom with 19 electrons: The element with 19 electrons is potassium (K).

Electron configuration of potassium: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1

Each electron configuration indicates the arrangement of electrons in the atom's energy levels and sublevels. The numbers and letters represent the main energy levels (n) and the types of sublevels (s, p, d, f) where the electrons are found. The superscripts denote the number of electrons occupying each sublevel.
