Answer:

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#

Explanation:

#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#)
