What is a period for periodic table?
The horizontal rows of the periodic table are called periods. Each period corresponds to the successive occupation of the orbitals in a valence shell of the atom, with the long periods corresponding to the occupation of the orbitals of a d subshell.What is period 4 on the periodic table?
The period 4 transition metals are scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), and zinc (Zn).

Article first time published onWhich element is in Group 3 Period 4?
Scandium (Sc) is the third element in the period, and is the first transition metal in the periodic table. Scandium is quite common in nature, but difficult to isolate because it is most prevalent in rare earth compounds, which are difficult to isolate elements from.
Which element is in period 4 Group 2?
The given element is calcium. The atomic number of calcium is 20.
What element is in Group 1 Period 6?
Group 1: Hydrogen is a gas and every other element in the group is a solid at room temperature. Period 6: They are all solids except for Radon and Mercury.
What element is in Group 1 Period 7?
Francium is a highly radioactive metal that decays into astatine, radium, and radon. As an alkali metal, it has one valence electron. Francium was discovered by Marguerite Perey in France (from which the element takes its name) in 1939.
What element is in Group 2 Period 5?
Rhodium: Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them.
What is the flammability of silicon?
Silicone is not considered to be flammable. It can catch fire and burn but requires high temperatures to do so. The ignition temperature of silicone is 842 degrees Fahrenheit (450 Celsius).
Is silicon made of sand?
Silicon is the second most common element in the earth’s crust, comprising about 26% and exceeded only by oxygen at 49%. … Not just any sand, but silica sand, specially quarried for this purpose and having concentrations of quartz (silicon dioxide) as high as 95%.

What element is in group 17 Period 2?
Group 17 occupies the second column from the right in the periodic table and contains fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
What is the history of silicon?
Silicon was discovered by Jöns Jacob Berzelius, a Swedish chemist, in 1824 by heating chips of potassium in a silica container and then carefully washing away the residual by-products. Silicon is the seventh most abundant element in the universe and the second most abundant element in the earth’s crust.
Is silicon a magnetic?
The surprise is that while bulk silicon is non-magnetic, the edges of nano-ribbons of this material are magnetic. … Most importantly, such stepped silicon-gold surfaces provide an atomically precise template for single-spin devices at the ultimate limit of high-density data storage and processing.
