Answer:
the number of neutrons in nucleus
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
Explanation:
An equation is said to be balanced when the number of atoms on both reactant and product side are equal in number.
Whereas an equation where electrolytes in an aqueous solution are represented as dissociated ions is known as an ionic equation.
For example, can be represented in ionic form as follows.
Now, cancelling the common ions present on both sides of the equation. The resulting, ionic equation will be as follows.
Answer:
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:
