Which has a greater electron affinity fluorine or bromine?

Fluorine has greater electron affinity than bromine, or any other element.

Is oxygen has more electron affinity than sulfur?

Yes. Oxygen has greater electron affinity than any other element except fluorine.

How do periodic trends in electronegativity relate to those for ionization energy and electron affinity?

The more positive the ionization energy and the more negative the electron affinity, the greater the electronegativity of an element.

Which has the lower electron affinity germanium or selenium?

Selenium has the greater electron affinity

What does high electron affinity mean?

electron = electron Affinity = Desire hence - high electron affinity is a molecule or ion that will draw electron to itslef and out of their orbitals and into their own orbitals eg electorphiles and cations. cation(+) + electron(-) --> Atom/molecule (no charge) Also the higher the electron affinity the greater the cation's/electrophiles pull on the electron

Why is the electron affinity for clorine is greater than the electron affinity for iodine?

As you move down in a group, electron affinity decreases, or becomes less negative. This occurs because it is further away from the nucleus and is less likely to accept an electron.

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.

Why electron affinity increases left to right?

In general, electron affinity does not increase steadily from left to right. Firstly, only non-metals have electron affinities greater than 0. Secondly, the ordering of these electron affinities is O<N<F; S<P<Cl

Why F has a higher electron affinity than C?

F is a group 7 element, so it only needs one electron to complete its octet, which would make it stable. Carbon on the other hand needs to give away 4 electrons or accept 4 electrons, which is much more difficult to make happen. Therefore, since fluorine needs less of a change to occur, and thus needs less electrons, it has a greater electron affinity

What are the factors that affect electron affinity?

Factors affecting the value of electron affinity(i) Atomic size: The value of electron affinity decreases with the increase in the size of atom since the nuclear attraction decreases down a group as the atomic number increases. Its value increases as we move along a period since the size of atoms decreases along a period. The lower value of Fthan Cl is due to the very small size of F in which negative charge is highly concentrated and repels the incoming electron thereby reducing the force of attraction of the nucleus towards the adding electron and hence decreasing the electron affinity. Thus, chlorine has a highest value of electron affinity.(ii) Nuclear charge: The value of electron affinity increases with increasing nuclear charge. Thus, its value increases with increase in nuclear charge along a period.(iii) Screening or shielding effect: The value of electron affinity increases with the decrease in shielding effect of inner electrons. Besides, the value of electron affinity also depends to some extent upon the type of orbital in which electron is added. The value is greater when electron enters 's' orbital and decreases successively for p, d and f orbitals.

Why ions with charges greater than 3 are seldom found in ionic compounds?

This is because the ionisation energy is too large for releasing the third electron to form chemical compounds or the electron affinity is too low for gaining the third electron when forming a chemical compound which will result in a low lattice energy to stabilise the ion.

What are the significance of Retention factor values?

Rf Values determine the solubility of a substance with respect to a certain solvent. It also determines the affinity of the solute to the solvent (greater Rf=greater affinity of solute to the solvent)

Why do alkali metals react in water?

Alkali metals are highly reactive because they have little electronegative affinity for their own valance electrons and so donate them readily to elements and molecules with greater electronegativity, or molecules with constituent element with greater electronegativity.

What is the significance of Rf value in chromatography?

· Used in identification pusposes · Use to determine the affinity of the solute to the solvent - Greater Rf , greater affinity of solute to the solvent

This element is the most reactive alkali metal has an atomic number greater than caesium and has one less valence electron than calcium?

This chemical element is francium (Fr).

What is the significance of the Rf values?

· Used in identification pusposes · Use to determine the affinity of the solute to the solvent - Greater Rf , greater affinity of solute to the solvent

Do ionic bonds share or transfer electrons?

Ionic bonds share atoms. An ionic bond is considered a bond where the ionic character is greater than the covalent character. Lithium has a low ionization energy and readily gives up its lone valence electron to the fluorine atom, which has a positive electron affinity and accepts the electron that was donated by the lithium atom.

How many time greater is the affinity of hemoglobin for carbon monoxide greater than the affinity of hemoglobin for oxygen?

The affinity of hemoglobin for CO is roughly 20,000 times greater than that of oxygen in vitro. In vivo, the affinity of hemoglobin for CO is roughly 200-225 greater than that of oxygen. ------------------------------------------------------------------------------------------------- O2 has stronger bond than CO. Therefore, the oxygen in CO loves the iron in the hemoglobin as iron ends with two electrons which complete the 6 electrons in the oxygen. In vivo, the affinity of hemglobin for CO is about 153 from 141x153/141. by amin elsersawi

Which subatomic particle has a greater mass a proton or an electron?

Proton has a greater mass than the electron.

The greater the distance of the electron from the nucleus the less energy it has?

No. The greater distance from the nucleus the more energy an electron has.

The farther an electron is from the nucleus the?

The farther an electron is from the nucleus, the greater its energy.

The relationship between hemoglobin and oxygen?

hemoglobin is the core of RBC'S and it has greater affinity to oxygen

Which element will have the greatest ionization energy?

Helium has the greatest ionization energy. Its electron is being removed from the principal shell closest to the nucleus. It has a greater I.E. than hydrogen does because the electron is being pulled away from a greater nuclear charge.

What is the reaction of fluorine with contact of water?

A displacement reaction,since due to greater electronegativity(greater affinity for hydrogen) fluorine displaces oxygen.

Why is there a sudden jump in the atomic radius in elements in group 18 and the next higher element in the next period in group 1?

When the element moves from group 18 to group 1, it moves to a new period. Each period has a one more electron shell than the previous. The group 1 element has one more electron shell than the group 18 element; hence, it's atomic radius is greater.
