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.
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.
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.
The element with 1 electron in period 1 would be hydrogen.
The period of an element is determined by electronic configuration.Period is same as the number of energy levels of the element.
Knowing the period of an element provides information about its electron configuration, specifically the highest energy level of electrons. Elements in the same period have the same number of electron shells, which affects their size and chemical reactivity. Generally, as you move across a period from left to right, elements become less metallic and more nonmetallic, with increasing electronegativity and ionization energy. Additionally, the period can indicate the element's potential bonding behavior and its position in the periodic table.
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.
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.
Increases from left to right in a period
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)
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.
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 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 with 1 electron in period 1 would be hydrogen.
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.
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 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 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.
