Question

3. When sodium metal is placed in a flask full of
chlorine gas, a violent reaction occurs. These
dangerous non-charged elements, when mixed,
produce the ionic compound sodium chloride,
otherwise known as table salt. Explain how this
happens in terms of nuclei, electrons, and charges.

Answer 1

Answer:

3 1/4

Explanation:

Answer 2

When sodium metal is placed in a flask full of chlorine gas, a violent reaction occurs and NaCL ( table salt ) is produced.

• Sodium (Na) and clorine (CL) forms an ionic bond.

What is an ionic bond?

An ionic bond is a chemical bond formed when one atom gives up one or more electrons to another atom. Ionic bonds are also known as electrovalent bonds.

2 Na ( s ) + Cl 2 ( g ) → 2 NaCl ( s ).

How do an ionic bond formed between Na and CL?

The attraction by chlorine is stronger than the attraction by sodium. An electron is transferred from sodium to chlorine. Sodium becomes a positive ion and chlorine becomes a negative ion. The positive and negative ions attract each other and form the ionic compound sodium chloride.

How this happens in terms of nuclei, electrons and charges?

• Sodium atom has one valence electron and chlorine also has one valence electrons.
• An electron is transferred from sodium to chlorine. Sodium becomes a positive ion and chlorine becomes a negative ion.

• sodium atom becomes positively charged and chlorine atom becomes negatively charged.
