Which element is the least reactive in period 4?
Noble gasses are least reactive of all the elements. So the least reactive element in the period 4 is Krypton. It is a noble gas with an atomic number of 36.
The atomic number of sodium the first element in Period 3 is 11 The atomic number of the second element in this period is?
it must be 12.
What is he element is found in the same period as sulfur and argon and that is more reactive than sulfur and argon?
Chlorine
Is sodium metal?
Sodium is a metal in Group 1 and Period 3 of the Periodic table. It is an alkali-metal.
Which element has chemical properties that are most similar to the chemical properties of sodium?
Potassium. Sodium is in group1 (period2) the next heaviest element is potassium (period 3). Potassium forms salts with the K+ ion.
What element is NaI?
Yes,Na represents an element. It is the symbol for sodium.Its atomic number is 11.Na stands for sodium. It locates in the 3rd period because it has electrons in three different energy levels. It is an alkali metal as it has only one electron in outermost shell.Yes, Na is an element in the 1st group. It is an alkaline metal. It is highly reactive.
As you go down a period does the element become more reactive or less reactive when placed in water?
more reactive
What is the characteristic of last element in each period of periodic table?
The last element in each period is a noble element. It is non-reactive.
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 common characteristics is generally shared by the element at the center of a period?
Least reactive
Which element is the least reactive in period 4?
Noble gasses are least reactive of all the elements. So the least reactive element in the period 4 is Krypton. It is a noble gas with an atomic number of 36.
Why is group 1 the most reactive element?
All metals are highly reactive because of their properties. As you move left on a period while moving down you move close to Francium (most-metallic). Since group 1 is the most farthest left group, it is the most metallic, therefore the most reactive.
What are the two highly reactive elements in period 4?
the metal potassium and the nonmetal bromine
Two highly reactive elements in period 2 are the metal lithium and what?
Nonmetal fluorine
What element is group 1 period 3?
Third period has 8 elements. They have 3 electron shells.
What is the largest element of Period 3 on the Periodic table?
Sodium has the largest atomic size in the third period.
