Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it.

Answer:

[Ne] 3s² 3p²

Explanation:

Since the 3s if now full we'll move to the 3p where we'll place the remaining two electrons. Therefore the Silicon electron configuration will be 1s²2s²2p^63s²3p². The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.

Answer:

Initial rate of the reaction when concentration of hydrogen gas is doubled will be $3.2\times 10^6 M/s$ .

Explanation:

$N_2+3H_2\rightarrow 2NH_3$

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

Initial rate of the reaction = R = $4.0\times 10^5 M/s$
