Draw a Lewis electron-dot diagram
for an atom of silicon in the ground
state.
| Answer--> Si
with 4 dots
...FYI Si is silcon not S |
54 Compare the
energy of an electron in the
first shell of a silicon atom to
the energy of an electron in the
third shell of the same atom.
| Answer-->The 3rd
shell electron has more
energy (it is in a
HIGHER energy level) |
55 Show a
numerical setup for calculating
the atomic mass of the element
silicon.
| Answer-->(
(27.98*92.22 ) +
(28.98*4.69) +
(29.97*3.09))/100 or the
remix
(27.98*0.9222 ) +
(28.98*0.0469) +
(29.97*0.0309) |
