What is the first element of the periodic table

Ionic bond is formed when there is a transfer of electron(s) from metallic atom to non-metallic atom.

The correct answer to the question is Option B. A bond resulting from the transfer of 1 or more electrons

Ionic bond exist between a metal and a nonmetal.

In this bonding, the metal losses it's valence electron to form a stable metallic ion, while the nonmetal receives the electron from the metal to form a stable nonmetallic ion which results in the formation of an ionic compound.

With the above information, we can see that ionic bond involves a transfer of electron(s).

Thus, the correct answer to the  question is Option B. A bond resulting from the transfer of 1 or more electrons.

Answer: B

Explanation:

Ionic bonding is the complete transfer of electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

The balanced chemical equation between solid chromium and solid iodine to form solid chromium(III) iodide is: 2 Cr(s) + 3 I₂(s) ⇒ 2 CrI₃(s)

Let's consider the unbalanced equation that occurs when ​solid chromium reacts with solid iodine to form solid chromium(III) iodide.​ This is a synthesis or combination reaction.

Cr(s) + I₂(s) ⇒ CrI₃(s)

We will balance it using the trial and error method.

First, we will balance I atoms by multiplying I₂ by 3 and CrI₃ by 2.

Cr(s) + 3 I₂(s) ⇒ 2 CrI₃(s)

Finally, we get the balanced equation by multiplying Cr by 2.

2 Cr(s) + 3 I₂(s) ⇒ 2 CrI₃(s)

Answer:

2 Cr(s) + 3 I2(s) → 2 CrI3(s)

Explanation:

Reactants:

Solid Chromium

• Chromium is a transition metal with an elemental symbol → Cr

• It can exist as a stable monatomic solid → Cr(s)

Solid Iodine

• Iodine is a non-metal halide of Group 7A → I

• It exists as a diatomic solid → I2(s)

Products:

Chromium(III) iodide

• Chromium, Cr → roman numeral III → +3 charge → Cr3+

• Iodide, I → from group 7A → -1 charge → I-

• When ions combine, their charges or oxidation numbers crisscross to become subscripts

• Cr will have a subscript of 1 from I- → Cr

• I will have a subscript of 3 from Cr3+ → I3

• Subscript 1 is no longer indicated → CrI3(s)

Unbalanced Chemical Reaction: Cr(s) + I2(s) → CrI3(s)

Balancing the chemical reaction:

1. Balance I:

Cr(s) + I2(s) → CrI3(s)

• There are 2 I in the reactant and 3 I in the product side

• Balance I by adding the coefficient 3 in I2 and 2 in CrI2

• There would be a total of 6 I in the reactant and product sides

Cr(s) + 3 I2(s) → 2 CrI3(s)

2. Balance Cr:

Cr(s) + 3 I2(s) → 2 CrI3(s)

• There is 1 Cr in the reactant and 2 Cr in the product side

• Balance Cr by adding the coefficient 2 in Cr(s)

• There would be a total of 2 Cr in the reactant and product sides

2 Cr(s) + 3 I2(s) → 2 CrI3(s)

Sodium Chloride (NaCl) can be classified as a salt

Explanation:

Sodium chloride is an "ionic compound" is known as salt. The ratio in which the  sodium(Na) and chloride(Cl) present in sodium chloride in  NaCl is  1:1. It is found in seawater and is accountable for the salinity of the seawater. Also, NaCl is the extracellular fluid for various multicellular organisms.  

When refined, it becomes in its 'edible' form and is used in food preservatives. Whereas, the large quantity of sodium chloride is used in various industries.
