Platinum/Atomic radius
The electronic configuration of platinum is: (Xe)(4f)14(5d)9(6s)1, and it has an atomic radius of 0.139 nm.
What determines the atomic radius of an element?
Atomic radius is determined as the distance between the nuclei of two identical atoms bonded together. The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group.
What is the atomic radius of palladium?

Palladium/Van der Waals radius
What is the symbol of platinum?
Pt
Platinum/Symbol
What does atomic radius depend on?
The value of atomic radii depends on the type of chemical bond in which the atoms are involved (metallic, ionic, or covalent bond). When the neighbouring atoms are not alike, as in sodium chloride, part of the observed distance between atoms is assigned to one kind of atom and the rest to the other kind.
What factors affect atomic radius?
Explanation of the general trends
factor | principle | effect on radius |
---|---|---|
nuclear charge | attractive force acting on electrons by protons in nucleus | decreases the atomic radius |
shielding | repulsive force acting on outermost shell electrons by inner electrons | increases the atomic radius |
Whats the difference between platinum and palladium?
Palladium is a harder metal than platinum, which means a palladium ring is harder to scratch compared to a platinum ring. As mentioned, if you don’t like the patina finish then re-polishing your ring will help restore the ring to near its original shiny look for both platinum and palladium.
What’s the atomic radius of xenon?

Xenon/Van der Waals radius
How do you find the radius of an atom?
How do you find the atomic radius? The atomic radius is calculated by measuring the distance between the nuclei of two identical atoms bonded together. Half this distance is the atomic radius.
How do you find the volume of a polonium atom?
Let’s calculate the atomic radius of polonium, which has molar mass = 209 g/mol, density = “9.32 g/cm”^3, and exists in a simple cubic unit cell. We see that there is 1 atom per unit cell (1/8 “atom” at each corner) and that the edge length of the cell (a) is twice the atomic radius (r). The volume of one atom is V_”atom” = 4/3πr^3.
How do elements in the same group have the same atomic radius?
Elements in the same period have the same number of electron shells, while elements in the same group have the same number of valence electrons. How do you find the atomic radius? The atomic radius is calculated by measuring the distance between the nuclei of two identical atoms bonded together. Half this distance is the atomic radius.
Which element has the smallest radius in the periodic table?
Which element has the smallest atomic radius? Helium has the smallest atomic radius at 31 picometers. Helium is in the top period and the farthest right group, which follows the patterns of atomic radius on the periodic table.
