Which atom has the greatest attraction for the electrons in a chemical bond Hydrogen Oxygen Silicon Sulfur?
1 Answer. for the above group ans. is oxygen.
Which atoms attract the most electrons?
Electronegativity is not measured in energy units, but is rather a relative scale. All elements are compared to one another, with the most electronegative element, fluorine, being assigned an electronegativity value of 3.98. Fluorine attracts electrons better than any other element.
Which atom has the weakest attraction for the electrons in a bond with an H atom?
Which atom has the weakest attraction for the electrons in a bond with an H atom? Sulfur has 2.6 electronegativity. Oxygen has a 3.4 electronegativity which is greater than nitrogen which has 3.0 electronegativity.
Which atom has a greater attraction for electrons sodium or chlorine?
Which atom has a greater attraction for electrons—sodium or chlorine? Which atom forms the negative ion? Chlorine has the highest electronegativity and therefore the strongest attraction. It also forms the negative ion and sodium forms a positive ion.
Which has highest electron affinity?
Chlorine Chlorine has the highest electron affinity among the elements. Its high affinity can be attributed to its large atomic radius, or size.
What is an electron attracted to?
All negatively charged electrons are attracted towards any positive charge, and a major source of positive charges are the protons at the center of the quantum atom. Shared electrons in a covalent bond, therefore, are pulled towards the positively charged protons at the centers of the two atoms.
Which element has the least attraction for electrons in A chemical bond?
Astatine Electronegativity describes an atom's ability to attract an electron. Lower electronegativity means a weaker ability to attract electrons. Astatine has the lowest ionization energy, electron affinity, and electronegativity of all the halogens.
Which atom has A greater attraction for electrons sodium or chlorine?
Which atom has a greater attraction for electrons—sodium or chlorine? Which atom forms the negative ion? Chlorine has the highest electronegativity and therefore the strongest attraction. It also forms the negative ion and sodium forms a positive ion.
Which element has the highest electron affinity?

- The electron affinity : …
- The halogen will have the highest electron affinity, while the noble gas will have the lowest electron affinity. …
- Fluorine has highest electron affinity in the periodic table.
Which element is most likely to gain electrons in a chemical reaction?
Nonmetals Nonmetals, which are found in the right-hand region of the periodic table, have relatively large ionization energies and therefore tend to gain electrons.
What attracts electrons to the nucleus?
The electrons are attracted to the nucleus by the electrostatic force of attraction to the protons. Surprisingly enough, although the minimum energy classically would have the electrons all located at the nucleus (point of strongest attraction) they aren't all there.
Are protons attracted to electrons?
The charge on the proton and electron are exactly the same size but opposite. Neutrons have no charge. Since opposite charges attract, protons and electrons attract each other.
Which element has the less attraction for electrons?
astatine All halogens have seven valence electrons, but as the atomic size increases, the attraction between the nucleus and these outer electrons decreases. The largest halogen atom is astatine. Therefore, astatine has the least attraction for electrons of all the halogens.
Which of the following has the greatest electron affinity?
Chlorine 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.
Which of the following has highest first electron affinity?
Electron affinities have positive values. However elements of group 2, 18 and N have zero values . Thus F has the highest electron affinity i.e., option ( a) is correct.
Which one of the following has largest electron affinity?
The electron affinity of O− is highest as the other given species have complete octet.
Which group of elements has the highest electron affinities?
Thus, nonmetals have a higher electron affinity than metals, meaning they are more likely to gain electrons than atoms with a lower electron affinity. For example, nonmetals like the elements in the halogens series in Group 17 have a higher electron affinity than the metals.
How do atoms attract electrons?
Covalent bonds form when electrons are shared between atoms and are attracted by the nuclei of both atoms. In pure covalent bonds, the electrons are shared equally. In polar covalent bonds, the electrons are shared unequally, as one atom exerts a stronger force of attraction on the electrons than the other.
Is electron attracted to neutron?
Unlike the proton which has a positive charge, the neutron has no electrical charge and does not attract an electron to the atom.
Which has the least attraction for electrons in a chemical bond?
Therefore, astatine has the least attraction for electrons of all the halogens.
Which atom has the least attraction for the electrons in a bond?
The element with the lowest electronegativity will have the least attraction for bonding electrons.
Which element has the least attraction for electrons?
All of an atom's positive charge is at its center. Electrons closer to the center are held more tightly as proton number increases. However, outermost electrons are held less tightly because inner electrons shield them. For this reason, it is astatine that has the least attraction for its outer electrons.
Which of the following atoms has the greatest tendency to gain electrons?
Fluorine Hence, the tendency to gain electrons increases. Fluorine has the greatest tendency to attract a shared pair of electrons and therefore it is known as the most electronegative element. Fluorine is the most electronegative element on the periodic table….Note:
| Ionisation Energy (KJ/mol) | |
|---|---|
| Fifth | 32820 |
Which of the following has the greatest electrons?
Therefore, chlorine has the greatest electron affinity than fluorine, and this orbital structure causes it to have the highest electron affinity of all of the elements.

What kind of charge are electrons attracted to?
All negatively charged electrons are attracted towards any positive charge, and a major source of positive charges are the protons at the center of the quantum atom. Shared electrons in a covalent bond, therefore, are pulled towards the positively charged protons at the centers of the two atoms.
What do electrons attract?
Since opposite charges attract each other, the negatively charged electrons are attracted to the positively charged protons.
Is an electron attracted to a proton?
But a proton and an electron attract each other. Another way of saying this is that the same or “like” charges repel one another and opposite charges attract one another. Since opposite charges attract each other, the negatively charged electrons are attracted to the positively charged protons.
