What is the lightest elementt is period 2?
The lightest element that is in period number 2 is lithium. Lithium is also the solid that is the least dense.
Is beryllium the most or least reactive in its group?
Beryllium is the least reactive in the group 2.
Which element is the most reactive out of nickel chlorine helium and iron?
The reactivity of an element increases towards the top and right of the periodic table (until the column of noble gases is reached). Chlorine's outer shell contains 7 electrons that make it very reactive. Helium is a noble gas and is non reactive. Elements found in the middle of the table, like nickel and iron, are reactive, but less reactive than chlorine
What element is in group iii period 2?
It is Boron.
Which element in the periodic table period 2 has the most mass?
Neon element in the periodic table period 2 has most mass.It has atomic mass of 20.17.It is colorless and odorless.
Which element of period 2 is the most reactive non metal?
fluorine
What are the 2 most reactive element found in the second period?
lithium and fluorine
What is the least reactive element in the group 2 of the periodic table of elements?
The Zinc Family also known as group IIB is the second least reactive I believe. The least reactive family is the one with a full p sublevel, the noble gases, the next least reactive would be the family with a full d sublevel. Since group IIB has a full d sublevel, it must be the next least reactive family.
What is the lightest elementt is period 2?
The lightest element that is in period number 2 is lithium. Lithium is also the solid that is the least dense.
What part of the periodic table is the most reactive and least reactive?
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
Is beryllium the most or least reactive in its group?
Beryllium is the least reactive in the group 2.

What period is the element neon in?
The element neon is in period 2. Classified as a non-metal. :)
What element is found in group 14 period 2?
what element is found between period 2 and group 14
What element is located in group 15 and period 2?
The element phosphorous (P) is located in group 15, period 2.
Which of the following elements is the least reactive?
