What is the electron affinity trend?
What is the trend for electron affinity? Electron Affinity increases across a period from left to right because of increasing effective nuclear charge and decreasing size of atoms. Electron Affinity decreases down the group due to increased size of atoms.
Which group has the highest electron affinity within a period?
Patterns in Electron Affinity. Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons.
Why do nonmetals have high electron affinity?
Nonmetals have a greater electron affinity than metals because their atomic structure allows them to gain electrons rather than lose them. …
What element is theoretically the largest of all on the periodic table?
What element is theoretically the largest of all on the periodic table? -Atomic radius increases as you move down the periodic table and to the left. Francium is the furthest down and to the left of this group and would be predicted to to be the largest element of the whole periodic table.
What has high electron affinity?
Which Element Has the Highest Electron Affinity? Chlorine has the highest electron affinity among the elements. Its high affinity can be attributed to its large atomic radius, or size. Because chlorine’s outermost orbital is 3p, its electrons have a large amount of space to share with an incoming electron.
How does electron affinity increase?
As the number of protons increase, the nucleus of the atom becomes more positively charged. The increase in positive charge increases the attraction between the nucleus and the electrons of the atom. Thus, the electrons are held more tightly towards the nucleus, increasing electron affinity.
Which has highest electron affinity?
Which of following has highest electron affinity?
Fluorine has highest electron affinity in the periodic table.
Which element has the smallest electron affinity?
The correct answer is Argon. Argon has all filled orbitals as well as a filled valence shell. As a result, it doesn’t want to lose or gain any electrons. Hence, argon has the lowest electron affinity.
Which of the following has the highest electron affinity?
What is the heaviest element?
There are 91 naturally occurring elements (but it depends on how you count them). The heaviest element that occurs in large quantity is uranium (atomic number 92).
Which element has the smallest size?
Thus, helium is the smallest element, and francium is the largest.
