Why do atoms of different elements form bonds?

Why do atoms of different elements form bonds?

Why form chemical bonds? The basic answer is that atoms are trying to reach the most stable (lowest-energy) state that they can. Many atoms become stable when their valence shell is filled with electrons or when they satisfy the octet rule (by having eight valence electrons).

What determines the number of bonds an atom can make?

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.

What is it called when two different atoms are bonded together?

Atoms can combine into ionic lattice structures or into covalent molecules. When different types of atoms combine, the result is called a compound.

When atoms combine they can make what?

When these atoms of the same or any kind combine they form molecules. Thus, two Hydrogen atoms combine to form a Hydrogen molecule. Most atoms can also combine with atoms of different kinds to form compounds of molecules.

Why does alcl3 not follow the octet rule?

1 Answer. Ernest Z. In some of its compounds, aluminum violates the octet rule by having only six valence electrons. For example, aluminum chloride, AlCl₃, has only six valence electrons around the Al atom….

Does pcl5 follow octet rule?

Phosphorus pentachloride: In the PCl5 molecule, the central phosphorus atom is bonded to five Cl atoms, thus having 10 bonding electrons and violating the octet rule.

Does ph3 obey octet rule?

Hydrogen has an electron configuration of 1s1 . Therefore, it has only one electron on top. Each of the three hydrogens will fill one of the empty spaces of the phosphorus atom in a covalent bond. This will provide eight electrons for phosphorus, to complete the rule of octet….

What type of bond exist in CCl4?
