When an ionic bond forms between lithium (Li) and fluorine (F), which of the following occurs?
2 answers:
Answer:
F gains one electron.
Explanation:
Hello,
Due to the high electronegativity of the fluorine atom (approx 3.98), it tends to gain electrons rather than lose them. Now, as lithium has the following electron configuration:
It loses one electron that is gained by the fluorine to form lithium fluoride, LiF.
Best regards.

Answer:
Pressure, P = 67.57 atm
Explanation:
<u>Given the following data;</u>
- Volume = 0.245 L
- Number of moles = 0.467 moles
- Temperature = 159°C
- Ideal gas constant, R = 0.08206 L·atm/mol·K
<u>Conversion:</u>
We would convert the value of the temperature in Celsius to Kelvin.
T = 273 + °C
T = 273 + 159
T = 432 Kelvin
To find the pressure of the gas, we would use the ideal gas law;
PV = nRT
Where;
- P is the pressure.
- V is the volume.
- n is the number of moles of substance.
- R is the ideal gas constant.
- T is the temperature.
Making P the subject of formula, we have;
Substituting into the formula, we have;
<em>Pressure, P = 67.57 atm</em>
