Across a period in the Periodic Table, atomic volume generally decreases from left to right. This decrease occurs because as the atomic number increases, the number of protons and electrons also increases, leading to a stronger effective nuclear charge. This stronger attraction pulls the electrons closer to the nucleus, resulting in a smaller atomic radius and thus a lower atomic volume. Consequently, despite the addition of electrons, the overall atomic size contracts, leading to a decrease in atomic volume across a period.

Define density and ampsize of elements across period and ampdown a group of periodic table?
Density generally increases across a period from left to right due to increasing atomic mass and the packing of atoms, while the atomic radius typically decreases. Conversely, density tends to increase down a group as atomic mass increases more significantly than atomic volume. Ampsize, or atomic size, generally decreases across a period due to increased nuclear charge, which pulls electrons closer to the nucleus. Down a group, ampsize increases due to the addition of electron shells, which outweighs the effect of increased nuclear charge.
What is nickels atomic volume?
The atomic volume of nickel is approximately 6.59 cubic centimeters per mole.
What element has highest atomic volume?
The element with the highest atomic volume is francium, which is a highly reactive alkali metal. Francium has the largest atomic radius of all the elements, leading to a high atomic volume.
How do you calculate atomic volume occupaied by Pt if atomic radius is 91.1Agstrom?
To calculate the atomic volume occupied by Pt, you can use the formula for the volume of a sphere, which is V = 4/3 * π * r^3. Given the atomic radius of Pt as 91.1 Å, you can substitute this value into the formula to find the atomic volume occupied by Pt.
How does density change by going down the periodic table?
As you go down the periodic table, the density generally increases. This is because the atomic mass and atomic size of elements increase as you move down a group, resulting in a greater mass packed into a larger volume. Exceptions can occur due to fluctuations in atomic structure or intermolecular forces.
What is potassium's atomic volume?
Atomic Volume (cc/mol): 45.3
What is nickels atomic volume?
The atomic volume of nickel is approximately 6.59 cubic centimeters per mole.
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 are the density trends in the periodic table and how do they impact the properties of elements?
The density of elements generally increases from left to right across a period in the periodic table and decreases down a group. This trend is due to the increasing atomic mass and decreasing atomic volume of elements. Higher density elements tend to have higher melting and boiling points, as well as greater hardness and strength.
What has atomic mass and volume?
