What is the change in atomic radii for the elements in period 2?
Seventeen
What does it mean if 2 elements are in the same period on the periodic table?
If two elements are in the same period on the periodic table, it means they have the same number of electron shells or energy levels in their atomic structure. As you move across a period from left to right, the elements typically exhibit increasing atomic numbers and varying chemical properties, as they gain additional electrons and protons. This arrangement reflects trends in reactivity, ionization energy, and electronegativity among the elements in that period.
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.
Which 2 elements in period 6 have the same relative atomic mass?
In period 6, the two elements that have the same relative atomic mass are lead (Pb) and thallium (Tl), both of which have an atomic mass of approximately 204.37 u. Their similar atomic masses can lead to some confusion, but they are distinct elements with different properties and uses in chemistry and industry.
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 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?

What is atomic number of mercury tetra thiocynatecobalt 2?
Only elements have atomic numbers, not compounds.
What does it mean if 2 elements are in the same period on the periodic table?
If two elements are in the same period on the periodic table, it means they have the same number of electron shells or energy levels in their atomic structure. As you move across a period from left to right, the elements typically exhibit increasing atomic numbers and varying chemical properties, as they gain additional electrons and protons. This arrangement reflects trends in reactivity, ionization energy, and electronegativity among the elements in that period.
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.
Which 2 elements in period 6 have the same relative atomic mass?

Their similar atomic masses can lead to some confusion, but they are distinct elements with different properties and uses in chemistry and industry.
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.
