What element has the highest atomic radius?
francium
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
Which is bigger O or F?
Explanation: From top to bottom of the periodic table ions will increase in radii. However, now left to right the radius is more of a function of the number of electrons. Similarly, O2- will be larger than F- as both have 10 electrons but Z=8 for oxygen and Z=9 for fluorine.
What is the atomic radius in chemistry?
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 atomic radius of an atom write the atomic radius of sodium?

What is the atomic radius of polonium?

What is the 103rd element?
lawrencium
Element 103 in the periodic table is called lawrencium. It was first synthesised in 1961 at what was then called the Lawrence Radiation Laboratory, situated close to San Francisco. The synthesis was carried out by a team of scientists led by Albert Ghiorso.
What element has an atomic number of 104?
Rutherfordium
Rutherfordium (Rf), an artificially produced radioactive transuranium element in Group IVb of the periodic table, atomic number 104. Soviet scientists at the Joint Institute for Nuclear Research at Dubna, Russia, U.S.S.R.
How did the element lawrencium get its name?
It is named in honor of Ernest Lawrence, inventor of the cyclotron, a device that was used to discover many artificial radioactive elements. A radioactive metal, lawrencium is the eleventh transuranic element and is also the final member of the actinide series.
How to find the atomic radius of an element?
Refer to graph, table and property element trend below for Atomic Radius of all the elements in the periodic table. We have shown the Atomic Radius of the elements for which reliable data is available. Mouseover on the chart to see the element name and Atomic Radius of the element.
Which is the most stable isotope of lawrencium?
Fourteen isotopes of lawrencium are currently known; the most stable is 266 Lr with a half-life of 11 hours, but the shorter-lived 260 Lr (half-life 2.7 minutes) is most commonly used in chemistry because it can be produced on a larger scale.
What is the atomic radius of carbon and nitrogen?
Atomic radius of Carbon (C) 170 pm. 7. Atomic radius of Nitrogen (N) 155 pm. 8. Atomic radius of Oxygen (O) 152 pm. 9.
