There are 18groups in modern periodic table.
- The modern periodic table is discovered by famous scientist Henry Mosley in 1914.
- The modern periodic table is also called long term periodic table.
- It has 7periods and 18groups.
It depends if the zinc ion lost or gained an electron. But electrons are more than 2,000 times smaller than a proton or neutron so small diffrence.
The correct answer is that anodization can produce a thin film around the metals, preventing rusting and other kinds of corrosion.
Anodizing refers to an electrolytic passivation procedure used to enhance the thickness of the natural oxide layer on the metal parts surface. The procedure is known as anodizing as the section to be treated produces the anode electrode of an electrolyte cell. The process enhances resistance to corrosion and rusting.
A use the half life of carbon 14 to find the value or the parameters b and plot the function
Answer: B(water)
Explanation:
Photosystem II uses energy from light to extract electron from water molecule to fill the hole left as the energized electron passes up the chain.When the electrons are removed from the water molecules,the water molecule breaks down into oxygen gas,which bubbles away, and hydrogen ions,which are used to power ATP synthesis.
