Answer:
The disadvantages or the limitations are as follows:
Dot structures: based on an empirical trend “atoms like octets”, not a rigorous description of the true nature of electrons
Arrow and line diagrams: Does not say much of the possible properties of the molecule.
Written electron configurations: no 3D representation of the molecule or the atom
Explanation:
please mark my answer as brain list
Answer:
0.00120 moles of electrons had traveled through the wire.
Explanation:
Amount current passed in 132 seconds = 0.880 A
Charge passed in 132 seconds = Q
Number of electrons = N
Magnitude of charge on an electron = q =
1 mole = ions/ particles/ atoms
The moles of electron in electrons:
0.00120 moles of electrons had traveled through the wire.
Answer: option C) 3.0
Explanation:
The electronegative value of an element indicates the power of its atom to attract an electron. It ranges from 0 to 4.
Ionic bond is formed between two elements with WIDE difference in electronegative values. e.g Sodium with 0.93 and Chlorine with 3.16 forms an ionic bond in NaCl with a difference of 2.23
Thus, a difference of up to 3.0 makes an ionic bond
