$[Ne]3s^2\3p^2$

Silicon has an atomic number of $14$ , so a neutral silicon atom would have $14$ electrons.

Therefore, it would have enough electrons to fill up till its $3p$ shell.

$1s^2\2s^2\2p^6\3s^2\3p^2$

We know that neon is a noble gas with an electron configuration of
$1s^2\2s^2\2p^6$ .

So, we can shorten silicon's electron configuration to a noble-gas configuration, which would be

$[Ne]3s^2\3p^2$
