explain the stucture of carbon tetrachloride with the help of electron dot diagram?

Carbon has four electrons in its outermost shell, so it requires four more electrons to complete the 8 electrons in the outermost shell.

Chlorine has seven electrons in its outermost shell, so it requires one more electron to complete the 8 electrons in the outermost shell.

Now, Carbon shares its four electrons with four chlorine atoms to achieve stable electronic configuration of eight electrons. In the process the four chlorine atoms too acquire the stable electronic configuration. The electron dot structure of Carbon tetrachloride can be drawn as:
