We have to know which do not violet octet rule.
The central atom in SF₄ does not violate the octet rule. the central atom in CF₄ does not violate the octet rule.
As per octet rule, atoms can combine either by transfer of valence electrons from one atom to another or by sharing of valence electrons in order to have an octet in their valence shell.
The central atom S of SF₄ contains 8 electrons in the valence shell. Also, C atom of CF₄ contains 8 electrons in the valence shell.
ICl₄⁻ contains 9 electrons in the outermost shell.
The answer is A - they are both polymers.
<h3>The somatic and sex chromosomes mainly differ in their Ploidy.</h3>
- Somatic Chromosomes are Diploid (2n)
- Sex Chromosomes are Haploid (n)
Haploidity of sex chromosomes enables the formation of a diploid zygote after fertilization
<h3>Somatic Chromosomes are homologous in nature while the Sex Chromosomes can be Analogous as in the case of Spermatozoa which bears XY genes </h3>
Answer: 1.90x10²³ atoms of O
Explanation: First convert the mass of O into moles:
5.06 g O x 1 mole O / 16 g O
= 0.32 moles O
Next use Avogadro's Number to find the number of atoms of O
0.32 moles O x 6.022x10²³ atoms O / 1 mole O
= 1.90x10²³ atoms O
MgCl2 because it is the only option in which a metal appears with a nonmetal. In this case, the metal transfers electrons to the nonmental because the metal has a lower ionization energy.
