Why do atoms want 8 valence electrons?

Neporo4naja [7]

Answer:

1) 8 valence electrons are a full shell that makes the atom more stable.

Explanation:

Due to the octet rule, atoms tend to form compounds in ways that give them eight valence electrons and thus give them the electron configuration of a noble gas, making them stable.

A sample of helium gas has a volume of 1.50 L at 159 K and 5.00 atm. When the gas is compressed to 0.200 L at 50.0 atm, the temp

Brums [2.3K]

Answer:

ghdtgfgrdvreeeegrwwggegteefewqrwefrwerrftrtdsfgyuytfgererdf

Explanation:

The given data is as follows.

$V_{1}$ = 1.50 L, $T_{1}$ = 159 K,

$P_{1}$ = 5.00 atm, $V_{2}$ = 0.2 L,

$T_{2}$ = ?, $P_{2}$ = 50.0 atm

And, according to ideal gas equation,

$\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}$

Hence, putting the given values into the above formula to calculate the value of final temperature as follows.

$\frac{5.0 atm \times 1.50 L}{159 K} = \frac{5 atm \times 0.2 L}{T_{2}}$

$T_{2}$ = 21.27 K

Thus, we can conclude that the final temperature is 21.27 K .
