Which element has the greatest electronegativity quizlet?

Which element has the greatest electronegativity? Fluorine. The most electronegative elements are at the top right of periodic table.

Which element has the greatest electronegativity?

Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.

Which is the element with the highest electronegativity value quizlet?

Fluorine (F) has the highest electronegativity (4.0). It does take electrons from the atoms of other elements.

Which is more electronegative N or O?

On the Pauling scale the electronegativity of nitrogen and oxygen are respectively 3.0 and 3.5. … Oxygen has 8 protons in the nucleus while nitrogen only has 7. A bonding pair will experience more attraction from the oxygen’s nucleus than from nitrogen’s, and so the electronegativity of oxygen is greater.

Is CL more electronegative than C?

At the bottom left corner of the periodic table lies Cesium, which lacks a catchy nickname [but has attracted a strangely devoted following] with an electronegativity of 0.79.
…
Carbon is More Electronegative Than You Think.

Which element has lowest electronegativity value?

The element with the lowest electronegativity value is francium, which has an electronegativity of 0.7. This value uses the Pauling scale to measure electronegativity. The Allen scale assigns the lowest electronegativity to cesium, with a value of 0.659.

What element in the second period has the largest?

Atomic Number of Beryllium. Lithium, is the largest element in the second period. Across the period this value decreases with fluorine having the lowest.

What element in the second period has the largest atomic radius group of answer choices?

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].

Why Sulphur is less electronegative than oxygen?

With oxygen, the bonding electrons are at the 2-level, and the 8 protons in the nucleus are shielded by the 2 electrons in the 1s orbital. … However, the bonding electrons in the sulphur are further from the nucleus, and so the attraction is lessened. So sulphur is less electronegative than oxygen.

What is the electronegativity difference of O and F?

List of Electronegativity Values of the Elements 2

Is n more electronegative than P?

Due to its small size, the net electron charge increases. Hence, its nucleus exerts greater force on the electrons. Thetefore, its tendency to gain electron is more as compared to that of Phosphorus. That is the reason why, Nitrogen is more electronegative element than Phosphorus.

Why is Cl more electronegative?

Oxygen is more electronegative than chlorine because of the following reasons : … Oxygen is placed towards the left side of fluorine so has one electron less than fluorine. Chlorine is below fluorine and has a new shell of valence electrons is added to it.

Why is Cl more electronegative than F?

The assertion states that Fluorine is more electronegative than Chlorine. … The reason states that Fluorine has higher electron affinity than Chlorine. Since fluorine has a very small atomic radius, it exerts a repulsive force on any incoming electron. Therefore, Chlorine has a higher electron affinity than Fluorine.

Which is more electronegative oxygen or chlorine?

Oxygen is more electronegative than Chlorine. Although when we move towards the right of the periodic table, electronegativity increases., but since the size of Chlorine is large, Consequently, the nucleus of oxygen attracts the electrons more than does the nucleus of chlorine.
