Covalent bonds are formed between CORRECT ANSWER nonmetals Why can a hydrogen atom form a covalent bond without fulfilling the octet rule? CORRECT ANSWER Hydrogen's valence shell can hold only up to two electrons. After a covalent bond has stabilized an atom, the atom will have CORRECT ANSWER a full valence electron shell. What best explains how two oxygen atoms, each with six valence electrons, can bond with each other? CORRECT ANSWER Each atom can share two electrons with the other s...

Describe the atomic differences between Ionic and Covalent bonds. 1. Ionic bonds form between ions and involve gain or loss of electrons, while covalent bonds occur when electrons are shared between two atoms What is the octet rule? List three types of elements that do not follow the octet rule and explain why. Octet rule=atoms tend to bond with other atoms so they have eight outer electrons in their valence shell 1. Elements with incomplete octets, includes: H, He, Li, Be, and B. 2. ...

GENERAL CHEMISTRY QUESTIONS AND ANSWERS | LATEST UPDATE | 2024/2025 | GRADED A+ What is the difference between an ionic bond and a covalent bond in terms of electron transfer and sharing? An ionic bond involves the transfer of electrons from one atom to another, creating positively and negatively charged ions, whereas a covalent bond involves the sharing of electron pairs between atoms. How does the concept of atomic orbitals explain the bonding in molecules? Atomic orbitals des...

The Octet Rule - correct answer Main group elements (groups 1, 2, and 13-17) tend to form bonds so that they have an "octet" of electrons (8 electrons) Noble gases - correct answer • Noble gases usually exist as single atoms and do not tend to form compounds; this is because they have completely filled orbitals. • Noble gases have filled s and p orbitals in the outermost shell Valence electrons - correct ans...

ATI TEAS 7 Test Chemistry - Chemical Bonds & Solutions (Answered) valence electrons The number of valence electrons in an atom is the most important factor in determining how an element will react. Valence electrons, which are found in an atom’s outermost energy level, are involved in forming chemical bonds. octet rule The octet rule states that atoms will lose, gain, or share electrons to obtain a stable electron configuration of eight valence electrons. In other words, if an atom nee...
