Answer:

O, S, Se, Te, Po

Explanation:

Oxygen, sulphur, selenium, tellurium and polonium are all members of group sixteen. The elements in group sixteen all possess six electrons in their outermost shell. Recall that an atom is said to stable if it contains eight electrons in its outermost shell. This is also referred to as the octet rule. Hence atoms of elements obey the octet rule when they combine to form compounds with eight electrons present on the outermost shell of each atom.

Having six electrons on their outermost shell implies that they need to gain two electrons by bonding to other atoms of other elements. Two examples will suffice here.

Water is formed when an oxygen atom shares an electron with each hydrogen atoms.

Hydrogen sulphide is formed when sulphur share two electrons with two hydrogen atoms. Hence the answer.

Answer:

O, S, Se, Te, Po

Explanation:

Hello,

In this case, when chemical bonds are formed, the valence electrons are the bridge to make it possible, nevertheless, the octet is the limit for the formation of bonds, that is, an element must not exceed 8 shared or gained electrons. In such a way, elements able to gain to electrons to attain the octet are those from the VIA group: O, S, Se, Te, Po, as they have six valence electrons, so two more electrons are suitable for attaining the octet.

Best regards.

A 2.4 L balloon holds 3.7 mol He. If 1.6 mol He are added to the balloon, what is the new volume?
Elanso [62]
For this question, lets apply Avagadro's law
when Pressure and temperature are constant, the volume occupied is directly proportional to the number of moles of gases.
\frac{V}{n} = k
where V-volume, n-number of moles and k - constant 
Therefore at 2 instances 
\frac{V1}{n1} =  \frac{V2}{n2}
where V1 and n1 are for 1st instance 
and V2 and n2 are for 2nd instance 
therefore 
\frac{V1}{n1} = \frac{V2}{n2}
V1 = 2.4 L
n1 = 3.7 mol
n2 = 3.7 + 1.6 = 5.3 mol
since more He moles are added at the 2nd instance its the sum of the moles.
V2 needs to be calculated \frac{2.4}{3.7}  = \frac{V2}{5.3}
V2 = 2.4 x 5.3 / 3.7
     = 3.4 L
Answer is 1st option 3.4 L
