Answer:
option "B" is correct (substance 2)
Answer:
ionic
Explanation:
Ionic bonds exist between Ca and F ions in CaF₂. Ionic bonds are interatomic bonds formed by the transfer of electrons from one atom to the other.
The donor atom here is Ca and it has two valence electrons. Fluorine is the receiving atom with 7 electrons in its outermost shell.
Ca would give one each of its two outermost electrons to the fluorine atoms to complete their octet. Ca ion would now resemble Argon and the flourine atoms would look more like Neon atoms.
This is an ionic bond
The best answer choice you could go for is B pure substance, a pure substance is a compound that is made of one element, like a diamond.
Answer:
Explanation:
The expression for centrifugal force is shown below as:-
Where, m is the mass of the object = ?
v is the velocity of the object = 7.60 m/s
r is the radius
F is the force = 222 N
Diamter = 11.6 m
Radius = d/2 = 11.6 m/2 = 5.8 m
Applying the values in the above expression as:-
Answer:
Ionic bonds are stronger than covalent bonds
