What type of bond exits between an element X with atomic number 12 and Y with atomic number 17?
Answer Details
Element X has atomic number 12, which means it has 12 protons in its nucleus. This also means that it has 12 electrons in its neutral state. Element Y has atomic number 17, which means it has 17 protons in its nucleus. This also means that it has 17 electrons in its neutral state.
To determine the type of bond between X and Y, we need to look at their electronegativity values. Electronegativity is the tendency of an atom to attract electrons towards itself in a chemical bond. X is a metal element and generally has low electronegativity values, while Y is a non-metal element and generally has high electronegativity values.
In this case, since X is a metal element and Y is a non-metal element, we can predict that the bond between them will be an electrovalent or ionic bond. An electrovalent bond is formed when electrons are transferred from a metal to a non-metal element. The metal element becomes positively charged and the non-metal element becomes negatively charged, forming ions. The attraction between the oppositely charged ions forms the electrovalent bond.
Therefore, the type of bond that exists between element X with atomic number 12 and Y with atomic number 17 is electrovalent or ionic.
Note: The term "electrovalent" is an older term for ionic bonds, which is why the option uses this term.
