What causes an ionic bond to form between sodium and chlorine?

An ionic bond forms between sodium and chlorine primarily because sodium atoms donate electrons and chlorine atoms gain electrons. Here's a brief explanation of the process:

• Sodium (Na) has one electron in its outermost shell (the third energy level, 3s¹). To achieve a stable electron configuration (similar to that of noble gases), sodium tends to lose this one electron, resulting in a positively charged ion (Na⁺).

• Chlorine (Cl), on the other hand, has seven electrons in its outermost shell (the third energy level, 3s²3p⁵). To achieve a stable electron configuration, chlorine needs one more electron. When it gains an electron from sodium, it becomes a negatively charged ion (Cl⁻).

As a result, the electrostatic attraction between the positively charged sodium ions (Na⁺) and the negatively charged chloride ions (Cl⁻) leads to the formation of an ionic bond. Thus, the correct answers from the options provided are:

• Sodium atoms donate electrons.
• Chlorine atoms gain electrons (though this option is not explicitly given).

So, in summary, the main contributing factor is that sodium donates electrons to chlorine, facilitating the formation of an ionic bond.

Which choice?

The most accurate choice from your options regarding the formation of an ionic bond between sodium and chlorine is:

Sodium atoms donate electrons.

This describes the key aspect of the ionic bond formation, where sodium donates one electron to chlorine, allowing both atoms to achieve stable electron configurations.

Fluorine has an atomic number 9. It is in period 2 of the periodic table. The diagram shows the electron dot diagram of a fluorine atom.

F with 2 dots each above, right, below and 1 dot left.

How many valence electrons are in an atom of fluorine?

two
seven
nine
seventeen

Fluorine has an atomic number of 9, which means it has 9 electrons in total. In the electron configuration, fluorine has 2 electrons in its first energy level (1s²) and 7 electrons in its second energy level (2s² 2p⁵).

The valence electrons are the electrons in the outermost electron shell, which for fluorine is the second shell. In the provided electron dot diagram, it shows 7 dots around the symbol for fluorine (F), representing its valence electrons.

Thus, the correct answer is:

Seven.

correct!!!
