What are the 21 to 30 elements?
scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc.
What is the strongest metal on earth?
Tungsten has the highest tensile strength of any pure metal – up to 500,000 psi at room temperature. Even at very high temperatures over 1,500°C, it has the highest tensile strength. However, tungsten metal is brittle, making it less useable in its pure state.
What is Y on the periodic table?
Y is the symbol for the element yttrium.
Where is thulium used?
Thulium has been used to create lasers. When stable thulium (Tm-169) is bombarded in a nuclear reactor it can later serve as a radiation source in portable X-ray devices. It also has potential use in ceramic magnetic materials called ferrites, which are used in microwave equipment.
Does the human body use thulium?
Thulium is used in lasers with surgical applications. Thulium has no known biological role. It is non-toxic.
Which is the ninth element in the periodic table?
Fluorine has the symbol F and is the ninth element in the periodic table. Normally, fluorine is a gas with a pale yellow color that is made up of diatomic molecules, F2. Fluorine is a very strong oxidizing agent because it attracts the highest number of electrons of all elements except chlorine.
Are there any elements in the eighth period?
, no element with a higher atomic number than oganesson has been successfully synthesized; all elements in the eighth period and beyond thus remain purely hypothetical.
Which is the seventh period of the periodic table?
Blocks (s, p, d, f.) An extended periodic table theorises about chemical elements beyond those currently known in the periodic table and proven up through oganesson, which completes the seventh period (row) in the periodic table at atomic number ( Z) 118. As of 2021
What is F in the periodic table of elements?
Fluorine has the symbol F and is the ninth element in the periodic table. Normally, fluorine is a gas with a pale yellow color that is made up of diatomic molecules, F2.
