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.
Which element is in group v of the periodic table and has 3 electron shells?
The element in group V of the periodic table with 3 electron shells is Phosphorus (P). Group V elements have 5 valence electrons and the number of electron shells corresponds to the period number on the periodic table, so a Group V element with 3 electron shells is in period 3.
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.
How does electron affinity vary in periods?
Increases from left to right in a period
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)
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.
Which element has 1 valence electron and is in period 1.?
The element with 1 electron in period 1 would be hydrogen.
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.
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 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.
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.
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.
