4. Which of the following elements does not want to have eight valence electrons? a. magnesium c. hydrogen b. oxygen d. nitrogen
Cloud [144]

Answer:

Hydrogen.

Explanation:

Hydrogen is the simplest chemical element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.

Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.

Based on the octet rule which states that atoms of chemical elements gain, lose or share electrons so as to have eight (8) electrons in their valence shell. Therefore, atoms of chemical elements bond in order to attain the electronic configuration of a noble gas i.e a full valence shell which comprises of eight (8) electrons.

However, the chemical element "Hydrogen" is an exception to the octet rule because it is only able to hold a maximum of two (2) valence electrons in its outermost shell to become full.

<em>Hence, Hydrogen is an element which does not want to have eight valence electrons. </em>

If a mutation occurs such that photosystem ii no longer functions as efficiently as it should, what might be most directly affec
ivolga24 [154]

Out of the following given choices;

a) The amount of oxygen produced

b) The rate of ATP synthesis by ATP synthase in the chloroplast

c) The rate at which NADPH is produced

d) The rate at which the protons are transported into the thylakoid

The answer is; A

The photosystem captures energy from sunlight and uses it to split a water molecule.   After splitting the water molecule (by taking an electron), the protein complex transports the electron to plastoquinone. The splitting of water molecules results in evolving of oxygen molecules. The hydrogen is what is used to reduce carbon dioxide to glucose.

Why would you not expect to find any photosynthetic organisms in the aphotic zone of a lake?
Delicious77 [7]

Answer:

There is little to no sunlight in the aphotic zone.

Explanation:

The aphotic zone is the deepest part of a lake/ocean, so no light is able to penetrate into those depths. Without light, photosynthetic organisms will not be able to undergo photosynthesis and will therefore not be able to survive.
