A covalent bond involves electrons being shared between atoms. The most stable state for an atom occurs when its valence electron shell is full, so atoms form covalent bonds, sharing their valence electrons, so that they achieve a more stable state by filling their valence electron shell.
What is it called when the electrons of one atom are attracted to the protons of another atom?
Ionic bonds are attractions between oppositely charged atoms or groups of atoms where electrons are donated and accepted.
What is the attraction of electrons from one element to another when bonded?
ionic bond
Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other. This attraction is known as an ionic bond.
Which atom attracts the electron pair in the bond more strongly?
When non-identical atoms are covalently bonded, the electron pair will be attracted more strongly to the atom that has the higher electronegativity. This results in a polar covalent bond.
What does an atom exhibit when it has a strong attraction for electrons they share with another atom?
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.
Which bond is formed when electrons are shared among atoms?
covalent bond
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
What is it called when an atom gives up one or more electrons to another atom?
An atom that loses one or more valence electrons to become a positively charged ion is known as a cation, while an atom that gains electrons and becomes negatively charged is known as an anion.
Which of the following has highest tendency to attract shared electrons?
Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79). This indicates that fluorine has a high tendency to gain electrons from other elements with lower electronegativities.
What has a strong attraction to electrons?
Elements with higher electronegativities, such as N, O, and F (fluorine), have a strong attraction for electrons in a chemical bond and will therefore “pull” electrons away from less electronegative atoms. Elements with low electronegativity, such as metals, tend to “give away” electrons easily.
What happens when atoms bond quizlet?
Atoms share their valence electrons in order to satisfy the octet rule. The nucleus of the opposite atom is then attracted to the first, and results in a molecule. A bond in which metal atoms “donate” valence electrons to a “sea” of electrons.
What is it called when electrons are being shared?
When electrons are shared between two atoms, they make a bond called a covalent bond.
What is a strong force of attraction holding atoms together in a molecule or crystal resulting from the sharing or transfer of electrons?
Strong chemical bonds are the intramolecular forces that hold atoms together in molecules. A strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals.
