An atom with one valence electron combines with an atom with seven valence electrons.

The atom with one valence electron is likely to lose its electron to form an ion with a +1 charge. 

The principle behind this is simple. Atoms wish to have a stable electronic configuration, which requires that their valence shell be complete. If an atom has only one valence electron, then in order to achieve stable configuration, it is easier for it to get rid of the electron and move back to its last completed shell instead of trying to gain 7 electrons to complete the current valence shell.

Question 7 of 15
Crazy boy [7]

Answer: 0.4 moles

Explanation:

Given that:

Volume of gas V = 11L

(since 1 liter = 1dm3

11L = 11dm3)

Temperature T = 25°C

Convert Celsius to Kelvin

(25°C + 273 = 298K)

Pressure P = 0.868 atm

Number of moles N = ?

Note that Molar gas constant R is a constant with a value of 0.00821 atm dm3 K-1 mol-1

Then, apply ideal gas equation

pV = nRT

0.868atm x 11dm3 = n x (0.00821 atm dm3 K-1 mol-1 x 298K)

9.548 atm dm3 = n x 24.47atm dm3mol-1

n = (9.548 atm dm3 / 24.47atm dm3 mol-1)

n = 0.4 moles

Thus, there are 0.4 moles of the gas.

What form of matter has a definite shape and takes up space?​
BARSIC [14]

Answer:

If something is in a solid state of matter, it has a definite shape and volume. The volume of an object is the amount of space it occupies. A block of wood placed on a table retains its shape and volume, therefore, it is an example of a solid. If a liquid is poured on that same table, there are very different results
