germanium (Ge), a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silvery-gray metalloid, intermediate in properties between the metals and the nonmetals.
What is the period for the element?
A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor.
What period are the following elements in N?
Nitrogen is the seventh element on the periodic table. It is located in period 2 and group 15.
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).What period is the element RB in?

What element is in group 16 Period 6?
oxygen group element, also called chalcogen, any of the six chemical elements making up Group 16 (VIa) of the periodic classification—namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv).
How many elements are in each period?
Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements. Periods 4 and 5 have 18 elements. Periods 6 and 7 have 32 elements because the two bottom rows that are separated from the rest of the table belong to those periods.What element is in period 3?
The third period contains eight elements: sodium, magnesium, aluminium, silicon, phosphorus, sulfur, chlorine, and argon. The first two, sodium and magnesium, are members of the s-block of the periodic table, while the others are members of the p-block.

How many elements are in the 3rd period?
The third period contains eight elements: sodium, magnesium, aluminium, silicon, phosphorus, sulfur, chlorine, and argon.
Is RB 72 stable?
Although rubidium is monoisotopic, rubidium in the Earth’s crust is composed of two isotopes: the stable 85Rb (72.2%) and the radioactive 87Rb (27.8%).
How many elements are there in 7th period?
The seventh period contains 32 elements, tied for the most with period 6, beginning with francium and ending with oganesson, the heaviest element currently discovered.

What element is in period 5 and Group 6?
Molybdenum is a Group 6 chemical element with the symbol Mo and atomic number 42.
What is found in Group 17 and Period 2?
The halogen elements are the six elements in Group 17 of the periodic table. 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 element that is found in Period 6 Group 18?
These gases all have similar properties under standard conditions: they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
What is period Number?
If you are given with the atomic number of an element you can find it’s period number and group number. The period number is related to the number of electron occupied shells in the element and the period number is linked to its valence electrons.
How many elements are in period 2 of the periodic table?
Period 2 only has two metals (lithium and beryllium) of eight elements, less than for any subsequent period both by number and by proportion.
What element is In period 3 Group 13?
boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).
What element is In Group 2 period 3?
3A(13)4A(14)5A(15)6A(16)
Why are period 3 elements called typical elements?
> The third period elements are called typical elements or representative elements because they represent the properties of their own group without anomalies. The third period consists of eight elements which are: sodium, magnesium, aluminium, silicon, phosphorus, sulfur, chlorine, and argon.
How do you find the period of an element?
To calculate the number of elements in a particular period, you need to note the individual subshells that belong to that period, and then sum up the number of the elements from those subshells.
Why does 5th period have 18 elements?
Complete step by step answer The order in which the energy of available orbitals 4d, 5s and 5p increases is \[5s < 4d < 5p\] and the total number of orbitals available are 9 and thus 18 electrons can be accommodated. In other words, in the fifth period, f orbitals are not filled.
What is normal period?
Though the average cycle is 28 days long, anything between 21 and 45 days is considered normal. That’s a 24-day difference. For the first year or two after menstruation begins, women tend to have longer cycles that don’t start at the same time every month. Older women often have shorter, more consistent cycles.
What element is in Group 7 Period 3?

What element is in group 13 Period 2?
The boron family contains elements in group 13 of the periodic talbe and include the semi-metal boron (B) and the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl).
