Moreover Na lies to the left of the periodic table and Cl lies to the right of the periodic table.

. Atomic radius means the distance between the farthest electron and the center of the nucleus. When two atoms form a covalent bond their electron clouds overlap. The third period will have larger atomic radius than the second period since the third period lies below the second period.

So Cl is also smaller than Na because Na is larger than Cl. Similarly Cl cation is smaller than Cl parent Atom. The element potassium K present in group 1 has the largest atomic radius.

C K K has the largest atomic radii because atomic radii decrease from left to right along a period. Sodium 227 pm. In determining the radius of an atom we have to consider the number of protons and the how many shells does this atom have.

Belongs to the 2nd period. Therefore according to the trend Cl has a larger radius because it is lower in the table. Barium symbolBa is the group 2 or alkaline earth metal that has the largest atomic radius equal to 222 pm.

Barium Ba will have the largest atomic size. The main reason for why the van der Waals radius is greater than the covalent radius is that it does not take into account overlap. What causes the trend for increasing atomic radius.

As we can see only Potassium has four electron shells therefore Potassium has the largest atomic size. Since potassium is located at the start of period 3 and bromine at the end of the same period potassium will have a larger atomic radius than bromine and thus the largest atomic radius of the four given atoms. Għalhekk O2 għandu minimu ta z-effettiv u għalhekk l-akbar raġġ.

Periodic Table Question Answer I have the largest atomic mass K Ca Sc Sc Im a member of the Halogen family S Cl Ar Cl I have the greatest electron affinity Al Si P P I have the largest atomic radius Ga Al Si Ga. The element which has the largest atomic radius is Cesium. Francium has the largest atomic radius since this atom contains the maximum number of shells with the lowest number of protons.

Helium has the smallest atomic radius. 7 troyadkins121 As you go down the table more electron shells are added to make the radius larger but as you go to the right the protons attraction increases so the radius actually shrinks. Which of the following atom has the largest atomic radius.

Hence Na has the largest atomic radius of the above-mentioned elements. Ab CIC Brd F 3Which elements has the electron configuration. A Na b Mg c K d Ca Answer.

In periodic table 3rd period will have larger atomic radius than the second period. They are cations and they are also positively charged ions. Helium 3A 13 4A 14 5A 15 6A 16.

Na has the largest atomic radius. You can confirm the answer by looking at an atomic radius table like this one Answer link. Hence the correct option is C.

Thus electron cloud is pulled more here and we can say size decreases in cation than parent atom. Since the boundary is not a well-defined physical entity there are various non-equivalent definitions of atomic radius. A Br b c Rb d Ga 2 Which of the following elements has the highest electronegativity.

The atomic radius of a chemical element is a measure of the size of its atom usually the mean or typical distance from the center of the nucleus to the outermost isolated electron. What is the atomic radii of sodium. Magnesium 173 pm.

Sodium Na Its atomic radius is 0190 nm and the 1 ionic radius is 095 nm. Na and Cl. Li is the largest because it has the smallest nuclear charge and.

Circle the atom in each pair that has the largest atomic radius. Now focus on potassium and bromine. Which of the following elements has the largest atomic size.

Atomic Radius is defined as the distance between the center of the nucleus and the outermost shell of an atom. Which element has the largest atomic radius. Question 9 Part A Of the following which atom has the largest atomic radius.

1 Which atom has the largest atomic radius. Question 9 Part A Of the following which atom has the largest atomic radius. Cesium has 6 orbital shells which means that it automatically is big.

Four widely used definitions of atomic. What elements have the smallest atomic radius. Br I K Rb.

Alternatively one can look at a Van der Waal radii table to find that the radii of the four elements are in picometres. Potassium 2882. Kif tista tgħid liema atomu huwa akbar.

Chemistry questions and answers. 152 2s22p6 3s2 a Beb Si c Mg d Kr 4 Which of the following has the largest radius. Down a group the number of energy levels n increases so there is a greater distance between the nucleus and the outermost orbital.

Hence K has the largest atomic radii. What element in the second period has the largest atomic radius. Atomic Radius is commonly known as one half of the distance between the nuclei of identical atoms that are bonded together.

CL has a larger Atomic Radius. In general atomic radius decreases across a period and increases down a group. Solved 1 Which atom has the largest atomic radius.

Allura ċ-Ċesju għandu l-akbar raġġ atomiku fost l-elementi mogħtija. Br I K Rb. From the above we can therefore say that the answer The atom in each pair that has the larger atomic radius are.

This is because of the increase in nuclear charge which tends to pull the electron closer to the nucleus and reduces the size of the atom. A f atom or o atom b ba atom or ra atom 88 c hf atom 72 or ti atom 22 d cs ion or ba ion e al ion or al atom f po ion 84 or at ion 85 Worksheet 3 3 periodic trends name period 1. Belong to the 3rd period.

What group has smallest atomic radius. The element which has the largest atomic radius is Cesium. Atomic Radius is defined as the distance between the center of the nucleus and the outermost shell of an atom.

Along a period the atomic radius decreases due to increase in nuclear charge and down a group the atomic radius or size of atom increases due to increase in a number of atomic shells thus Na will have a largest atomic radius. Hence Na has largest atomic radius. Oxygen 152 pm.

Again Cl lies to the right and Na lies to the left of the periodic.
