The element is Si (Silicon)
More about Silicon
silicon (Si), a nonmetallic chemical element in the carbon family (Group 14 [IVa] of the periodic table). Silicon makes up 27.7 percent of Earth’s crust; it is the second most abundant element in the crust, being surpassed only by oxygen.
Silicon is a naturally occurring mineral. It's the second-most abundant element on earth after oxygen. Food sources include water, fruits, and vegetables.
Silicon supplements are sometimes used as medicine. It's not clear if silicon has a function in the human body. But there's some evidence it might have a role in forming bone and collagen.
People use silicon for weak bones (osteoporosis), aging skin, and many other conditions, but there is no good scientific evidence to support most of these uses.
Do not confuse silicon with silicone. Silicone is a group of materials resembling plastic that are used to make medical devices.

Yes, because if its higher than their will be more aquatic life able to live their.
<u>Answer:</u>
<em>Two atoms of the same element are most likely to form Molecule.</em>
<em></em>
<u>Explanation:</u>
are some examples
1 molecule of fluorine contains 2 atoms of Fluorine.
Similarly,
One molecule of chlorine (Cl),
One molecule of bromine (Br),
One molecule of iodine (I)
Each contains two atoms of the same element. We call these molecules as homodiatomic molecules.
There are 7 diatomic molecules which are as follows,
They are and
Answer: The original mass of the sample of Uranium-235 is 0.7308 mg
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
a) for calculating rate constant
b) for time of years
The original mass of the sample of Uranium-235 is 0.7308 mg
