Why chlorine has a higher electrongativity value than iodine?
Chlorine has a higher electronegativity than iodine because it is smaller in size, leading to a stronger effective nuclear charge that attracts electrons more strongly. Additionally, chlorine belongs to a higher group in the periodic table, which increases its electronegativity due to greater shielding effects.
What best describes a bond formed between two unlike atoms?
A bond formed between two unlike atoms is typically an ionic bond, where one atom will transfer electrons to the other to achieve a stable configuration. This results in the formation of ions that are attracted to each other due to their opposite charges. Ionic bonds are usually strong and lead to the formation of ionic compounds.
What describes a bond formed between two unlike atoms?
The type of bond is determined by the difference in electrongativity of atoms
Does F2 have polar bonds?
Yes, F2 has polar bonds. Fluorine is more electronegative than other elements, so there is a significant difference in electronegativity between the two atoms in the bond, resulting in a polar covalent bond.
What is the electrongativity of silver?

What element has the highest electrongativity of elements?
A fluorine atom has a higher electronegativity than an atom of any other element.
What is a bond formed between two unlike atoms?
An ionic bond is formed between two unlike atoms when one atom transfers electrons to another, resulting in a transfer of charge. This type of bond is typically formed between a metal and a nonmetal.
What is the electrongativity of potassium?
The electronegativity of potassium (K) is approximately 0.82 on the Pauling scale. This relatively low value indicates that potassium is not very effective at attracting electrons in a chemical bond, which is consistent with its classification as an alkali metal. Alkali metals tend to have low electronegativities due to their large atomic radii and the presence of a single electron in their outermost shell.
Why chlorine has a higher electrongativity value than iodine?
Chlorine has a higher electronegativity than iodine because it is smaller in size, leading to a stronger effective nuclear charge that attracts electrons more strongly. Additionally, chlorine belongs to a higher group in the periodic table, which increases its electronegativity due to greater shielding effects.
What is the periodic trend for electrongativity?
Electronegativity generally increases from left to right across a period and decreases from top to bottom within a group on the periodic table. This trend is due to the increasing nuclear charge across a period and the increasing distance between the nucleus and valence electrons down a group.

Which elements on the periodic have the lowest electrongativity?
The elements with the lowest electronegativity are found in Group 1 of the periodic table, specifically cesium (Cs) and francium (Fr). These alkali metals have very low electronegativity values due to their single valence electron, which they readily lose in chemical reactions. As a result, they have a weak ability to attract electrons from other atoms. Overall, cesium is typically recognized as the least electronegative element, with a Pauling scale value of about 0.79.
What statement describes a periodic trend of electrongativity?
Electronegativity generally increases across a period from left to right on the periodic table due to the increasing nuclear charge, which attracts bonding electrons more strongly. Conversely, it tends to decrease down a group as the distance between the nucleus and the valence electrons increases and the shielding effect from inner electrons reduces the nucleus's pull on bonding electrons. Consequently, elements in the upper right corner of the periodic table, like fluorine, exhibit the highest electronegativity.
Does F2 have polar bonds?
Yes, F2 has polar bonds. Fluorine is more electronegative than other elements, so there is a significant difference in electronegativity between the two atoms in the bond, resulting in a polar covalent bond.
