Both Bromine with an atomic number of 35 and Potassium with an atomic number of 19 both belong to group 4. The 'rule' is that the atomic radius increases across the group from Group One to Eight. This can be proven true.
As you move across the a period from left to right, the amount shell remains the same however an electron is added on to the final orbital. In the case of potassium which has only one shell on the final shell, that electron is shielded from the pull of the nucleus by the third shell of electrons and as such the shell is able to float further away from the rest of the shells thus making a larger atom on a whole. In the case of Bromine the number of electrons it has on the fourth shell (one down from the octet) is pulled heavily toward the nucleus because the increase in the number of protons in the nucleus thus seeing where its shells are closer to the nucleus therefore contributing to a smaller atomic radius.
Just so that you will always remember this here is a picture to remind you always.
Answer:
Hi, the statements given in the question (a and b) are combination of right and wrong answers. But i will split the statement a and b into necessary fragments.
Carbohydrates are quick source of energy relatively. That is the only correct statement in the question.
Explanation:
Carbohydrates are naturally occurring organic compounds containing carbon, hydrogen and oxygen with the general formula (Cx H2y Oy) or Cx (H2O)y. They can be classified into simple sugar or complex sugar.
Simple sugars can be further divided into Monosaccharides (e.g glucose, fructose and galactose) and Disaccharides (e.g sucrose and maltose).
Complex sugar can be referred to as Polysaccharides (e.g cellulose and starch)
The statement above that says carbohydrate contains carbon, hydrogen and nitrogen polymers is not correct.
Carbohydrates are not mostly monosaccharides. They also contain Disaccharides and Polysaccharides.
They are not the only source of fuel.
Answer:
glycerol-3-phosphate, ADP, H⁺
Explanation:
The reaction of converting glycerol to glycerol-3-phosphate which makes is unfavorable and is coupled with the second reaction which involves conversion of ATP to ADP which is high energetically favorable.
Reaction 1: Glycerol + HPO₄²⁻ ⇒ Glycerol-3-phosphate + water
Reaction 2: ATP + H₂O ⇒ ADP + HPO₄²⁻ + H⁺
The coupled reaction of both the reactions become favorable. Thus, the overall coupled reaction is:
<u>Glycerol + ATP ⇒ Glycerol-3-phosphate + ADP + H⁺</u>
The net products are = glycerol-3-phosphate, ADP, H⁺
KI or "Potassium Iodide" is a combination between a metal (potassium) and a nonmetal (iodine). In order to bond, iodine has to accept an electron from potassium, making them both ions. This combination between a metal cation and a nonmetal anion is an ionic bond.
