Question

question 16
what type of chemical bond can form between an atom with 11 protons and an atom with 17 protons?
non - polar covalent
ionic
polar covalent
hydrogen

Explanation:

1. First, determine the elements: An atom with 11 protons is sodium (Na), and an atom with 17 protons is chlorine (Cl).
2. Sodium is a metal (alkali metal) and chlorine is a non - metal (halogen).
3. Metals and non - metals typically form ionic bonds by transferring electrons (sodium loses an electron to become \(Na^+\), chlorine gains an electron to become \(Cl^-\), and they are held together by electrostatic attraction).

• Non - polar covalent bonds form between atoms of the same element or atoms with similar electronegativities sharing electrons equally, which is not the case here.
• Polar covalent bonds form between non - metals with different electronegativities sharing electrons unequally, but the large electronegativity difference between Na and Cl (and the metal - non - metal nature) leads to ionic, not polar covalent, bonding.
• Hydrogen bonds are intermolecular forces, not chemical bonds between these two atoms.

Answer:

B. ionic
