Answer:

A

Explanation:

An element from group 17 wants to gain an electron to from a negative ion. A metal forms only positive ions, an element from group 1 will lose to form a positive ion and elements with eight valence electrons are normally very stable, meaning they don't need to lose or gain.

Answer:

A

Explanation:

In other options, they form positive ion as they have extra electrons in their valence shell

But in group 17, all the elements have 7 electrons in their valence shell,inorder to attain octet they require one more electron

Hence,they form negative ion by gaining electron

Define disphotic zone?
Llana [10]

Explanation:

The photic zone, euphotic zone, epipelagic zone, or sunlit zone is the uppermost layer of a body of water that receives sunlight, allowing phytoplankton to perform photosynthesis. It undergoes a series of physical, chemical, and biological processes that supply nutrients into the upper water column. The photic zone is home to the majority of aquatic life due to its location.

Photosynthesis in photic zone Edit

In the photic zone, the photosynthesis rate exceeds the respiration rate. This is due to the abundant solar energy which is used as an energy source for photosynthesis by primary producers such as phytoplankton. These phytoplankton grow extremely quickly because of sunlight's heavy influence, enabling it to be produced at a fast rate. In fact, ninety five percent of photosynthesis in the ocean occurs in the photic zone. Therefore, if we go deeper, beyond the photic zone, such as into the compensation point, there is little to no phytoplankton, because of insufficient sunlight.[1] The zone which extends from the base of the euphotic zone to about 200 meters is sometimes called the dysphotic zone.[2]
