The element fluorine has 9 electrons. Which is the electron configuration for an atom of fluorine?

The electron configuration for an atom of fluorine is [He]2s2.2p5.


An atom of fluorine has 9 electrons.Its second energy level has?

The second energy level of an atom of fluorine will have 7 electrons. This is because the first energy level can hold a maximum of 2 electrons, and the second energy level can hold a maximum of 8 electrons. Since fluorine has a total of 9 electrons, 2 of them will be in the first energy level and 7 will be in the second energy level.


How many electrons does a fluorine atom have in its second shell?

A fluorine atom has 7 electrons in total. In its second shell, fluorine will have a maximum of 8 electrons, but since it has 7 electrons already in the first shell, it will only have 1 electron in the second shell.


What is the electron configuration for the fluorine atom?

The electron configuration for a fluorine atom is 1s2 2s2 2p5. This means there are 2 electrons in the first energy level, 2 electrons in the second energy level, and 5 electrons in the p orbital of the second energy level.


How many valence electrons are there in a fluorine atom?

There are 7 valence electrons in a fluorine atom. Fluorine is in group 17 of the periodic table, so it has 7 electrons in its outermost energy level.


What is the Bohr-Rutherford diagram of the fluorine atom?

The Bohr-Rutherford diagram of a fluorine atom would show 9 protons and 9 electrons arranged in three energy levels with 2 electrons in the first energy level and 7 electrons in the second energy level. The outer energy level would contain 7 electrons, giving fluorine a full valence shell and making it a reactive nonmetal.


How many number of electron shells does fluorine atom have?

A fluorine atom has 2 electron shells. The first shell can hold up to 2 electrons, and the second shell can hold up to 8 electrons, giving a total of 10 electrons for a fluorine atom.


How many electrons does fluorine atom have in its outermost unexcited main energy level?

A fluorine atom has 7 electrons in its outermost unexcited main energy level. This allows fluorine to achieve a full valence shell of 8 electrons by gaining one additional electron through bonding.
