Question

B) Write the electron dot structure for Sodium and chlorine atoms.
c) Write any two properties of ionic compound​

Answer 1

Answer:

Answer

The reactivity of the elements is determined by the tendency to have a completely filled valence shell. The electron dot structure of Na (sodium) and Cl (chlorine) atoms are shown in the figure 1.

Electron dot structure of Na and Cl

To attain completely filled valence shell, Na has to lose the outermost electron, and Cl needs one electron to complete the valence shell.

By losing an electron, Na becomes Na

+

(cation ) and this electron is accepted by Cl to form Cl

−

(anion) . The oppositely

Answer 2

Answer:

Sodium have one electron in its valence shell and chlorine have 7 electrons in its valence shell and it requires only one electron to complete its octet that electron is donated by sodium and thus a bond is formed between the two atoms.
