look on the periodic table of the elements Na and Si!

$Na^11$ = $1s^2 2s^2 2p^6 3s^1$ and

$Si^14$ = $1s^2 2s^2 2p^6 3s^2 3p^2$

$Na^11$ = $1s^2 2s^2 2p^6 3s^1$ and

$Si^14$ = $1s^2 2s^2 2p^6 3s^2 3p^2$ $=>$ Excited state $=>$ $1s^2 2s^2 2p^6 3s^1p^3$

Silicon is in the same carbon family, so remember the organic chemistry of carbon, it has sp3 hybridization and makes 4 bonds.

The Lewis dot structure of $Na^4Si$ is tetrahedral structure!

With sigma bonds ( $s-sp^3$ )
