The three broad classes of elements are:
Metals
Metalloids
Nonmetals
Answer:
8.32 s⁻¹
Explanation:
Given that:
The concentration of myosin = 25 pmol/L
R_max = 208 pmol/L/s
The objective is to determine the turnover number of the enzyme molecule myosin, which has a single active site.
In a single active site of enzyme is known to be a region where there is binding of between substrate molecules, thereafter undergoing chemical reaction.
The turnover number of the enzyme is said to be the number of these substrate molecule which binds together are being converted into products.
The turnover number of the enzyme molecule of myosin can be calculated by the expression: 
⇒ 
= 8.32 s⁻¹
Answer:
Explanation:
Question 1:
atomic number/number of protons
All atoms of the same element share the same number of protons or atomic numbers. In grouping elements on the periodic table, the periodic law is often used. The modern periodic law states that "properties of elements are a periodic function of their atomic number". The atomic number of an element distinguish it from others.
Question 2:
The two carbon atoms would be quite different as they are isotopes. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei.
Naturally, carbon exists in two isotopic forms:
¹³₆C and ¹⁴₆C
One might see these different samples in a rock and in the skin cells. They are simply isotopes. Isotopes have the same electronic configuration and hence similar chemical properties. Only their masses differ.
