What do elements in each period have in common?
they have the same energy levels
How many elements in the first period?
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
What do periods and groups have in common in a periodic table?
Every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. It goes down the periodic table like that. This also means that the atomic weight of the elements gets larger and larger in each period.
What period is potassium k located?
Potassium (K) is a metal in Group I of the Periodic Table of the Elements. K has an atomic number of 19 and a molecular weight of 39.10 grams per mole.
How many shells do the 4th period elements have?
Every element in the first period has only one orbit. This means that they can have only a duplet in their valence shell, which happens to be their only electronic shell. The elements included in the first period are Hydrogen and Helium.
What do the elements in a period have in common?
NOTHIN !
What common characteristic is generally shared by the elements at the center of a period?
they are the least reactive elements
What do elements in each period have in common?
they have the same energy levels
Do elements in the same group or elements in the same period have more in common?
GROUPS have more in common than PERIODS. I don't know why, I just know the answer.From, Bryan Hollick
What common characteristics is generally shared by the elements at the center of a period?
Least reactive
What common characteristics is generally share by the elements at the center of a period?
Least reactive
What do the atoms in elements in period 3 have in common?
Three electrons in their valency orbit.
Do the elements Na Mg Al Si P S Cl Ar have anything in common?
All of these elements belong to same period. The period number is 3.
How many elements in the first period?
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
How many elements can the 3rd shell hold?
The 3rd shell can contain 18 electrons. The elements that have a 3rd shell as the outer shell are the the elements in period 3, where the 3s and 3p orbitals are filled to a maximum of 8 electrons. The 3d orbitals are filled in the 4th period in the transition elements.
What is an elements period?
A period is a row of elements
What has the chemical symbol As?
Arsenic, which is in the 15th group 4th period of the periodic table of elements and has an atomic number of 33.
