How do you calculate atomic radius?

How do you calculate atomic radius?

Divide the distance between the nuclei of the atoms by two if the bond is covalent. For example, if you know the distance between the nuclei of two covalently bonded atoms is 100 picometers (pm), the radius of each individual atom is 50 pm.

How is Zeff calculated?

The effective nuclear charge is the net positive charge experienced by valence electrons. It can be approximated by the equation: Zeff = Z – S, where Z is the atomic number and S is the number of shielding electrons.

Is polonium most radioactive element?

The polonium is also rare chemical element as radium which carry the atomic number 84, as the radium it is also one of the radioactivity elements. The polonium is very expensive element that can be extracted out from the ore of the uranium.

How to find atomic radii?

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 way does the atomic radius increase?

The atomic radius increases as one goes down a group in the periodic table because more electrons are around the atom and more neutons and protons are present. As one goes across a period the atomic radius decreases because more protons are in the atoms as one goes across the period and the electrons are in the same shell.

What is the oxidation number of polonium?

In compounds of polonium (where known), the most common oxidation numbers of polonium are: 4, 2, and -2.
