Explanation: Fluorine has the greatest attraction for electrons in any bond that it forms. The attraction of an atom for shared electrons is called its electronegativity.
Which type of elements tends to have the greatest attraction for electrons?
The higher the electronegativity value of an atom, the greater its attraction for bonded electrons. Nonmetals typically have the highest electronegativity values and therefore the greatest attraction for bonded electrons.
Which type of element has a stronger attraction for electrons large atoms or small atoms?
Therefore, attraction for the electrons of another atoms is greater for smaller atoms than for larger. In smaller atoms the nucleus is closer to the surface of the electron cloud and can exert more attractive force on the electrons of another atom.
What element has most electrons?
| Oganesson | Electrons per shell 2, 8, 18, 32, 32, 18, 8 (predicted) | Physical properties | Phase at STP solid (predicted) |

Which element has the weakest attraction to electrons of other elements?
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 metal has lowest ionization energy?
From this trend, Cesium is said to have the lowest ionization energy and Fluorine is said to have the highest ionization energy (with the exception of Helium and Neon).
Which group has the highest electronegativity?
Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79).
What element is most attractive?
An element that is highly electronegative, such as fluorine , has an extremely high attraction for bonding electrons. Elements at the opposite end of the spectrum, such as highly reactive metals cesium and francium, readily form bonds with electronegative atoms.
How do you attract electrons?
Electronegativity is a property that describes the tendency of an atom to attract electrons (or electron density) toward itself. An atom’s electronegativity is affected by both its atomic number and the size of the atom. The higher its electronegativity, the more an element attracts electrons.
Which elements lose electrons most easily?
In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li). In fact, for the alkali metals (the elements in Group 1), the ease of giving up an electron varies as follows: Cs > Rb > K > Na > Li with Cs the most likely, and Li the least likely, to lose an electron.
What element has most neutrons?
Uranium , for example, has the largest naturally occurring nucleus with 92 protons and over 140 neutrons. where, A is the mass number of the element’s nuclei, and Z is the atomic number (X stands for the element symbol, for example: H is for hydrogen, O is for oxygen, Na for sodium, etc.)
Is there a 119 element?
Ununennium , also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119.
What is the highest energy level?
What is it meant by the highest occupied energy level in an atom? The highest occupied energy level in an atom is the electron-containing main energy level with the highest number .
Which atoms will bond when valence electrons are transferred?
Ionic bonds are a class of chemical bonds that result from the exchange of one or more valence electrons from one atom, typically a metal, to another, typically a nonmetal. This electron exchange results in an electrostatic attraction between the two atoms called an ionic bond.
Which compound has both ionic and covalent bonding?
Calcium carbonate is another example of a compound with both ionic and covalent bonds. Here calcium acts as the cation, with the carbonate species as the anion. These species share an ionic bond, while the carbon and oxygen atoms in carbonate are covalently bonded.
Which compound contains ionic bonds?
Ionic compounds contain ions and are held together by the attractive forces among the oppositely charged ions. Common salt (sodium chloride) is one of the best-known ionic compounds. Molecular compounds contain discrete molecules, which are held together by sharing electrons (covalent bonding).
