<span>then for the Henderson-Hasselbalch equation: </span>
<span>9.00=9.25527+log(.600/acid) </span>
10^(-.25527)=(.600/acid)correct to this line. Then 
0.5556 = 0.6/acid and 
acid = 0.6/0.5556 = 1.08 which is the reciprocal of your number)

P: Good conductor of heat and electricity - R: the delocalized electrons are
free to move around the structure

P: High melting and boiling points - R: the bonds in metals are very strong

P: Ductile (can be stretched and squashed) - R: because the electrons are free to move, the atoms can slide over each other.

P: Malleable (can be hammered into shape) - R: the bonds in metal don't break easily

Answer:

1s² 2s²2p³  

Explanation:

If the atom has seven electrons, it is Element 7 (nitrogen).

In the Periodic Table, you count the electrons in all the subshells up to

No. 7.

In the first Period, you have filled the 1s level (2 electrons).

In the second Period, you have filled the 2s subshell (2 electrons) and put three electrons in the 2p subshell.

Thus, the electron configuration is

1s² 2s²2p³

Note how the superscripts tell you the number of electrons in each subshell: <em>2 + 2 + 3 = 7</em>.
