Quick Answer: Which element in the second period has the largest atomic radius?

The element in the second period that has the largest atomic radius is the Lithium (Li).

What element in Period 2 has the largest atomic radius?

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 of the following element of second period has second highest radius?

Properties of Elements in Period 2 of the Periodic Table

What elements have the largest atomic radius?

Francium has the largest, Helium has the lowest. Atomic radius increases as you go to the left and downward due to the attraction of electrons and the nucleus in an atom.

What element in the second period has the largest atomic radius group of answer choices carbon lithium potassium neon?

Answer Expert Verified

The elements in the second period are lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon. In the second period, the atomic radius of the elements decreases across the period, thus lithium has the highest atomic radius of 152 picometer while neon has the least [67 picometer].

What has the smallest atomic radius?

Explanation: Helium has the smallest atomic radius. This is due to trends in the periodic table, and the effective nuclear charge that holds the valence electrons close to the nucleus.

How do you find atomic radius?

The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance. As you can see from the diagrams, the same atom could be found to have a different radius depending on what was around it. The left hand diagram shows bonded atoms.

Which element has the smallest atomic radius in second period?

As we move from left to right, atomic size decreases because of increase in nuclear charge but no change in the shells. Hence, Last element will be the smallest element in the period. Hence, fluorine has small radius in the second period.

Which element has the smallest atomic radius quizlet?

Therefore, rubidium has the largest atomic radius whereas helium has the smallest.

What is the atomic radius of neon?

154 pm

Is Br or Br bigger?

Br – will have the largest atomic size because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius of Br- will increase.

Does S or O have a larger atomic radius?

Consequently for the neutral atoms, S would be larger than O. For the sulfide ion, reinforcing this effect is the large, excess 2- charge that greatly increases the radius of S2- as compared with the neutral S atom.

Which has largest radius?

Thus O2− has a minimum z-effective thus largest radius.

Which element in Period 2 is the most active metal?

Fluorine is the most reactive of all elements, and it even attacks many oxides to replace oxygen with fluorine. Fluorine even attacks silica, one of the favored materials for transporting strong acids, and burns asbestos.

What is the period for nitrogen?

Which element has the largest atomic radius as NP?

Antimony(Sb) has the largest atomic radius because it has more number of shells as compensation to the other elements..
