How are the elements arrange in the periodic table?
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
What is the symbol equation for metal and oxygen?
Use the letter 'M' . The number of oxygen atoms in the metal oxide depends on the Group in the periodic table. Group (I) = M2O Group(II) = MO Group (III) = M2O3 Group (IV) = MO2 The transition metal have variable oxidations. They can be M2O, M2O3 , MO, M3O4
Why 3rd and 5th group elements only are used in the manufacture of optoelectronic devices?
Well they are not. Silicon is used in solar panels - an optoelectronic device. What is true that the nature of the semiconductors made by reacting group 13 and group 15 (old school group III and group V) generically called the III/V semiconductors. Examples are Gallium nitride, gallium phosphide, gallium arsenide, indium phosphide. The key is the nature of the band gap and how this can be affected by doping. Gallium nitride is used in many applications, and is used with suitable doping in blu-ray disc reader laser diodes
What are the elements present in Iron III hydroxide?
Iron, oxygen and hydrogen are found in Fe(OH)3.
What is the formula for chromium III sulfide?
Chromium III is Cr3+. The roman numeral tells you the charge. Sulfide is S2-. You can figure this out from the periodic table. Sulfur needs two electrons to be like Argon, the next noble gas. When they form a compound, they combine in a ratio such that the total positive charge balances the total negative charge. 2 Cr3+ ions have a total charge of +6. 3 S2- ions have a total charge of -6. So the formula is Cr2S3.
How many elements are in transition metals?
transition metals are not in any groups, however they are elements between group II & III of the periodic table
What group has the most elements on the periodic table?
Group III-B or 4th, it includes 4 elements of 'd' block and all the 28 elements of 'f' block.
What is the location of MnBr3 in the periodic table?
MnBr3 is the chemical formula for Manganese(III) Bromide. Manganese (Mn) is a transition metal located in Group 7 of the periodic table. Bromine (Br) is a halogen located in Group 17.
What group in the periodic table is lanthanide series?
(iii)b
In which group is classified on the periodic table aluminium?
Group 'III'
What are the elements on the right side of the periodic table called?
Noble gases: helium, neon, argon, krypton, xenon, radon, ununoctium.
What are the main group elements of the periodic table?
Main group elements have elements from groups 1 and 2, except hydrogen and groups 13 to 18. Main group elements are elements in groups who's lightest elements are shown by helium, lithium, boron, beryllium, carbon, nitrogen, oxygen, and fluorine.
How are the elements arrange in the periodic table?
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
What is the most common oxidation number for group three on the periodic table?
Generally third A group elements in the periodic table exhibit +3 oxidation state but Boron exhibit negative oxidation state also . The stable oxidation state of Tl is +1. It exhibit +3 also but +1 is more stable than +3. RGUKT IIIT NUZVID N091528
What is the section of the metals on the periodic table of elements called?
Old Style - called Groups : I A, II A, III A with the exception of Boron, III B through to VIII B, and I B & II B.
What family forms ions with a charge of 3?
Elements in groups 3 and 13 in the periodic table and some transition metals are capable of forming +III ions.
Which groups make up the transitional metals?
Groups 3-12
