What is the change in atomic radii for the elements in period 2?
Seventeen
Why does the change for the atomic radii of the elements for period 3 from sodium to argon look similar to period 2?
Because the trend is the same. Atomic radius decreases from left to right across a period.
How many elements are there in the first period of periodic table?
There are 2 elements in the first period of the periodic table: Hydrogen and Helium.
What is the period and group number for the element with an atomic number of 88?
Radium (atomic no. 88): Group 2 (Alkaline Earth Metals), period 7 of the periodic table of elements.
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 is the general trend in densities for period 2?
The general trend in densities for period 2 elements of the periodic table is that densities increase from left to right. This is because elements in period 2 have increasing atomic numbers, leading to an increase in atomic mass and a decrease in atomic volume, resulting in higher densities.
What is the change in atomic radii for the elements in period 2?
Seventeen
What is atomic number of mercury tetra thiocynatecobalt 2?
Only elements have atomic numbers, not compounds.
Why are the elements 94 through 110 in the periodic table whole numbers?
1. All the atomic numbers are whole numbers. 2. If you think to atomic weight of heavy radioactive elements (atomic numbers from 93 to 118) is a rule of IUPAC to indicate in square parenthesis, [], the atomic mass of the most stable or known isotope.
What is the chang ein the atomic radio for the elements in period 2 from lithium to neon?
42
Which element in the 2 period has the greatest atomic radius?
Neon (Ne) in the second period on the periodic table of the elements has the highest atomic number in that period of 10.
Why does the change for the atomic radii of the elements for period 3 from sodium to argon look similar to period 2?
Because the trend is the same. Atomic radius decreases from left to right across a period.
How many elements are there in the first period of periodic table?
There are 2 elements in the first period of the periodic table: Hydrogen and Helium.
Why does the change for the atomic radii of elements in period 3 from sodium to argon look similar to period 2?
The atomic radii of elements in period 3 from sodium to argon decrease due to a greater nuclear charge pulling electrons closer to the nucleus. This trend is similar to period 2 because both periods follow the same pattern of increasing nuclear charge as you move across the period, leading to a similar decrease in atomic radii.
What Element is in group 2 period 2?
Ba, Barium, Atomic #56, is in Group-2 Period-6 of the Periodic Table of the Elements.
What is the period and group number for the element with an atomic number of 88?
Radium (atomic no. 88): Group 2 (Alkaline Earth Metals), period 7 of the periodic table of elements.
What is the name of the element in group 2 period 3?
there is no element found in such a place because that spot doesn't exist. there is a period 4-7 but not 1-3 for group 6. that particular spot is open and doesn't include any elements
