Tin, because it has five energy levels with four electrons in the fifth level
.
Explanation:
Tin has an electronic configuration as
1s2,2s2,2p6,3s2,...........4d10, 5s2,5p2
They have four valence electrons in their outer shell
Among the four diagrams given Tin is least reactive because the atomic radius of tin is largest among all four options. Due to large atomic radius electronegativity decreases and hence Tin is the least reactive element among Neon, Chlorine, gallium and tin.
The electronegativity of an element is its tendency to complete its octet by attracting electrons towards itself. Also tin is at the lowest place in the periodic table among all the four mentioned elements, its ionization energy is also low hence less electronegative and least reactive.
Answer:
The Central dogma includes the replication, transcription and translation.
Explanation:
RNA polymerase; It is invloved in transcription process in which the the squence of DNA is coppied to RNA known as mRNA.
Spliceosomes; The genetic information is in non-continuous form i.e introns (non-codding sequences) are present between exons. These introns are removed by spliceosomes from pre-mRNA.
Codons; Codon is the sequence of three nucleotides on mRNA that code for specific amino acid i.e AUG for methionine.
Ribosomes; These are known as protein factory because protein synthesis take place in ribosomes.
tRNA; It brought the specific amino acids for corressponding codon on mRNA for polypeptide chain.
