Answer 1

Answer:

Hee Sun drew an electron dot diagram of a silicon atom as shown.

S i with 1 dot each above, right, below, left.

In addition to changing the symbol to C, how would this diagram compare with an electron dot diagram of a carbon atom (C)?

The dot to the left of the symbol would be removed in the diagram for carbon.

The same number of dots would appear in the diagram for carbon.

There would be two dots above and to the right of the symbol in the diagram for carbon.

The single dots would be replaced with two dots on each side of the symbol in the diagram for carbon.ion
