An ionic compound is composed of ionic bonds that are formed by transfer of electrons from one atom to the other. The atom that loses electrons acquires a positive charge (cation) while that which gains electrons acquires a negative charge.
In the case of sodium chloride; Sodium Na has 1 electron in its outer orbital while Chlorine Cl has 7 electrons. Thus, Cl requires 1 electron to complete its octet. This electron is donated by Na.
Thus, NaCl is essentially, Na⁺Cl⁻
Ans D) Chlorine becomes an anion by gaining an electron from sodium
Cans aren't entirely made of tin because of rusting. When scratched(which happens quite frequently to cans) the tin is in more danger of rusting. This is why the cans are coated in a layer of tin rather than the whole can is made of it.
Answer:
Light energy acts as a catalyst that speeds up the rate of photosynthesis
Explanation:
Answer: 2.408×10^24 atoms
Explanation:
Applying the formula
No. moles= (no. Of atoms)/Avogadro's number
4 = n/6.02×10^23
no. of atoms= 2.408×10^24 atoms
