In Period 3 of the Periodic Table, chlorine (Cl) has the highest electron affinity. This is due to its strong tendency to gain an electron to achieve a stable noble gas configuration, which is that of argon. Chlorine's high electronegativity and effective nuclear charge also contribute to its significant ability to attract additional electrons.
What else can I help you with?
Is electron affinity of N is greater than F?
No, it is not. Electron affinity follows a trend like electronegativity and hence increases as we move from left to right across a period. So, Fluorine has the highest electron affinity among 1st period elements.
If an element is the last element in its period what does this mean?
On the Periodic Table, a Period is one of the horizontal rows. If an element is last in it's period, then it's on the right hand side of the Periodic Table. There is an inert gas at the end of every Period.
Which element has 1 valence electron and is in period 1.?
The element with 1 electron in period 1 would be hydrogen.
Why is the period of an element determined by an electron configuration?
The period of an element is determined by electronic configuration.Period is same as the number of energy levels of the element.
What information does the period number of an element give you?
The period number of an element indicates the highest energy level that electrons occupy in an atom of that element. It corresponds to the row in the periodic table where the element is located, with each period representing a new principal energy level. For example, elements in period 2 have their outermost electrons in the second energy level. Additionally, the period number can give insights into the element's electron configuration and overall chemical properties.
Is electron affinity of N is greater than F?
No, it is not. Electron affinity follows a trend like electronegativity and hence increases as we move from left to right across a period. So, Fluorine has the highest electron affinity among 1st period elements.
What is the trend for electrons?
As you go across a period; Left to right, the electron affinity increases. As you go down a group; top to bottom, the electron affinity decreases.
What are the trends and exceptions to the trends in electron affinity?
Down the group electron affinity decreases Across a period electron affinity increases. However, it should be noted that chlorine is having higher electron affinity than flourine due to the small size of fluorine atom)
How does electron affinity vary in periods?
Increases from left to right in a period
If an element is the last element in its period what does this mean?
On the Periodic Table, a Period is one of the horizontal rows. If an element is last in it's period, then it's on the right hand side of the Periodic Table. There is an inert gas at the end of every Period.
Which element pf the 4th period has highest ionisation energy?
krypton because it is an inert/noble gas, which means it has a complete outer shell and takes a lot of energy to remove an electron.
Electron affinity tends to what?
Electron affinity is an elements' ability to attract electrons and is variable for each element. Generally the more electronegative atoms are furthest to the right bottom of the periodic table and ascending to the left the elements lose their electron accepting ability.
Which element has 1 valence electron and is in period 1.?
The element with 1 electron in period 1 would be hydrogen.
The element in period 3 that has the highest ionization energy is?
Argon (#18). It's a noble gas, which means it doesn't react, which means it will be really hard to get it to lose an electron.
What is a group and the period?
Rows of elements are called periods. The period number of an element signifies the highest unexcited energy level for an electron in that element. Columns of elements help define element groups. Elements within a group share several common properties. Groups are elements have the same outer electron arrangement.
What can the period of a element be determined by?
The period of an element in the periodic table can be determined by the number of electron shells or energy levels that the element's atoms have. Each period on the periodic table corresponds to the number of electron shells occupied by the elements within that period.
The period of an element can be determined by what?
The period of an element can be determined by its electron configuration, specifically the highest energy level that contains electrons. The period corresponds to the number of electron shells in the atom's structure. Each period represents a new energy level or shell being filled with electrons.
