Answer: The correct option is e.
Explanation: In the given question it is asked to tell the element which has 'Sea of electrons' while bonding.
This means that the element should have extra electrons so that it can bond easily or this also means which element can easily donate its electron to form a bond.
- Electronic configuration of Hydrogen =
Hydrogen cannot loose electrons easily because the electron is present in 1s sub-shell which is the closest to the nucleus and hence will be tightly bonded to it.
- Electronic configuration of Helium =
This element will not loose electrons easily because the 1s sub-shell is fully filled and hence will not be available for bonding.
- Electronic configuration of Sulfur =
This element lacks 2 electrons from attaining stable configurations. Hence, it will gain 2 electrons rather than donating for bonding.
- Electronic configuration of Iodine =
This element lacks 1 electron to attain stable configuration. Hence, it will gain 1 electron rather than donating for bonding.
- Electronic configuration of Lithium =
This element has an extra electron in its valence shell and can be easily lost in order to form bond.
Hence, the correct option is e.
The blank space in the task statement should be filled with 25 as methane can retain 25 times more heat than carbon dioxide.
<h3>Heat Retention: Methane and Carbon dioxide</h3>
Methane, carbon dioxide amongst other gases are important greenhouse gases which allows the Earth retain it's heat in order for it to be habitable.
Methane can retain and release about 25 times more heat than Carbon Dioxide although Methane emissions are lower compared to Carbon Dioxide.

Plasma's are gases of electrically charged particles, with equal amounts of both positive and negative charge. Only certain types of particles, called bosons, can form Bose-Einstein condensates. The other type of particle- Fermions- can only have at most one particle in each state.
Answer:
Answer is Object 2 (which has a density of 1.9 g/cm³).
Explanation;
When object is floating, the weight of that object is less than the up thrust on it.
When an object fully submerged and floating, then the weight of that object is equal to the up thrust on it.
This is known as the Archemide's principle.
Both up thrust and weight depends on the density. Hence, if the density of the solution is high, then the up thrust also high. If the density high, the the weight of the object also high.
Hence, to sink the object in water, that object should be denser than water. Hence, answer is object 3 which has a higher density than water.
