Why is Silver called AG?
The symbol Ag derives from the Latin argentum and Sanskrit argunas from “bright”. … The Latin word for silver is argentum. Silver has been known since ancient times.
Whats the difference between magnesium and manganese?
The key difference between Manganese and Magnesium is that the Manganese (Mn) is a transition metal in the d-block of the periodic table, whereas Magnesium (Mg) is an alkaline earth metal in s-block. Both Magnesium and Manganese have similar uses as well, but their function and properties are different.

Why are lanthanides called lanthanides?
The lanthanides are the 14 elements from cerium (atomic number 58) to lutetium (atomic number 71). The word comes from the Greek “lanthanein” meaning “to be hidden.” The name probably arose because these elements all hide behind one another in the periodic table.

Why is copper a CU?
The name derives from the Latin cuprum for Cyprus, the island where the Romans first obtained copper. The symbol Cu also comes from the Latin cuprum. … From the Latin word cuprum, from the island of Cyprus. It is believed that copper has been mined for 5,000 years.
Where is manganese found in the body?
The human body contains about 10 to 20 mg manganese, of which 25% to 40% is in bone [1,2]. The liver, pancreas, kidney, and brain also contain manganese. The body maintains stable tissue manganese concentrations through regulatory control of manganese absorption and excretion .
What does manganese do to the body?
Manganese is a trace mineral that is present in tiny amounts in the body. It is found mostly in bones, the liver, kidneys, and pancreas. Manganese helps the body form connective tissue, bones, blood clotting factors, and sex hormones.
Is manganese a metal?
A hard, brittle, silvery metal. Manganese is too brittle to be of much use as a pure metal. It is mainly used in alloys, such as steel.
What has the atomic number 29?
copperFor April, we have selected copper, a transition metal with chemical symbol Cu and atomic number 29.
What do you call the element from atomic number 57 71?
The elements from atomic number 57 to 71 are called Lanthanides. They are called lanthanides, since lanthanum is chemically identical to the elements in the sequence. … The lanthanides are between Barium and Hafnium.
Which number is atomic mass?
Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
What do you call the element from atomic number 58 71?
The Lanthanides. The lanthanides , elements 58-71, follow lanthanum on the periodic table.
