Question

there are three types of chemical bonds: covalent, ionic, and metallic. the type of chemical bond formed between two atoms depends, in part, on the number of valence electrons in each atom. valence electrons are located in the outermost energy level, or valence shell, of an atom. the attractive force between one atoms nucleus and the valence electrons of another atom pulls the atoms close together. as they approach one another, the atoms may share or transfer valence electrons to create a chemical bond. valence electrons are the only electrons involved in chemical bonding. this model shows the attractive forces between a sodium (na) atom and a chlorine (cl) atom. sodium transfers a valence electron to chlorine to form table salt (nacl). select the true statements. a chlorine atom has seven valence electrons. valence electrons can be shared between atoms or transferred from one atom to the other. a chemical bond forms when electrons of one atom are attracted to electrons of another atom. atoms combine by forming metallic, covalent, or ionic bonds.

Explanation:

• Chlorine is in group 17 of the periodic table and has 7 valence electrons.
• Valence - electrons participate in sharing (covalent bonds) or transfer (ionic bonds) during chemical bonding.
• Chemical bonds form due to the attraction between the nucleus of one atom and the valence - electrons of another atom, not just electron - electron attraction. But the statement about sharing/transferring valence electrons is correct in the context of bond formation.
• The three main types of chemical bonds are metallic, covalent, and ionic, and atoms combine through these types of bonds.

Answer:

A. A chlorine atom has seven valence electrons.
B. Valence electrons can be shared between atoms or transferred from one atom to the other.
D. Atoms combine by forming metallic, covalent, or ionic bonds.
