Answer:
NaCl= ionic bond.
H2O=covalent bond.
Explanation:
NaCl:
Happens between metal and non-metal. since metal needs to lose an electron to get a full outer shell of electrons, sodium (Na) loses one electron and has a full outer shell of electrons.
chlorine is a gas so it needs to gain electrons to have a full outer shell. since it is in group 7, it needs to gain 1 electron for a full outer shell of electrons.
the lost electron from sodium is given to chlorine. this creates ions (a charged particle) so it is Na+Cl-. this creates a strong electrostatic attraction between the elements and causes them to join together in a lattice form.
H2O:
Covalent bonds happens between 2 gases. they share an electron or 2, and the bonds are very strong.
since oxygen needs 2 molecules to form a full outer shell. hydrogen have 1 atom in outer shell so they share the electron with the oxygen atom.
I can't fully explain why this is for H2O, but I hope you understand it.
Krypton is the only element that begins with the letter K.
C because we need materials in the lab
the bond will break
The bond will dissolve (break) if the electron absorbs a photon and is moved from a bonding molecular orbital to an antibonding orbital since there is no longer an overall stabilizing interaction.
<h3>What is an antibonding orbital?</h3>
An antibonding molecular orbital is the molecular orbital created by the destructive overlapping of atomic orbitals.
<h3>Why is it called antibonding orbital?</h3>
- Every atom will add one electron to the bond that makes up the lower energy bond.
- To prevent interacting with the other two electrons, the additional electron will occupy a higher energy state.
- The antibonding orbital is the name of this higher energy orbital.
<h3>What orbitals form an antibond?</h3>
- The bonding orbitals are home to electrons that spend the majority of their time between the nuclei of two atoms, whereas the antibonding orbitals are home to electrons that spend the majority of their time outside the nuclei of two atoms.
<h3>When an electron was elevated to the antibonding orbital, what happened?</h3>
- In contrast, putting electrons in antibonding orbitals will make the molecule less stable.
- The energy levels of the orbitals will determine how many electrons are filled.
- The lower energy orbitals will be filled first, and then the higher energy orbitals.
