Question

the atomic numbers of elements H and M are 12 and 17 respectively. determine the molecular formula of the compound formed when these two elements react with each other. explain the type of bond formed between those two elements with the help of electron dot structure




please fast okk 3 Mark's answers plzzzzzzzz​

Answer 1

Answer:

Explanation:

The number of bonds for a neutral atom is equal to the number of electrons in the full valence shell (2 or 8 electrons) minus the number of valence electrons. This method works because each covalent bond that an atom forms adds another electron to an atoms valence shell without changing its charge.

Answer 2

The molecular formula of the compound formed by combining H and M is HM4.

• H has an electronic configuration of 2,8,4 .
• M has an electronic configuration of 2,8,7.
• So inorder to attain octet M needs one electron while H requires 4 electrons.
• This can be achieved by covalently bonding 4 M atoms to one H atom .
• Hence, the molecular formula is HM4.
• In a covalent bond both the atoms contribute one electon each and the pair of electrons is shared by both the atoms.
