Answer:

Yes , covalency fails to explain the formation of BeCl₂ and PCl₅.

Explanation:

covalent bonds are formed between two atoms by sharing of outermost electrons in order to attain octet for attaining stability . To octet means to attain 8 electrons in their outermost orbit .

BeCl₂ :

Be has two electrons in its outermost orbit and each of Cl has 7 electrons .

Each of Cl shares one electron each with each of two electrons of Be . Cl atoms attain 8 electrons as octet . But Be attains only 4 electrons ( 2 of Be and 2 from Cl atoms ) . Hence octet of Be is not attained . So covalency fails in the formation of BeCl₂ .

PCl₅ :

P has 5 electrons in the outermost orbit . Each of these electrons shares with one electron from each of Cl atoms . Thus Cl attains octel state ( 8 electrons ) but P attains 10 electrons ( 5 + 5 ) , 5 of P and 5 from 5 Cl atoms .

Hence Octet of P is not attained . Hence covalency fails in the formation of PCl₅ .

An object's mass is less on the Moon than it is on Earth.

vovikov84 [41]

Answer:

The mass of objects remains constant throughout the universe. This is because an object is made of he same amount of matter (atoms), no matter where you take it in the universe. If you take an object from the Earth to the moon, only the weight will change.

Close all network ports, filter those you can't block

Firewalls are used to filter network traffic and are available as standard system software on most operating systems. Limit the openings hackers have to your server.
