5f− inner transition series of elements are placed separately at the bottom of the periodic table. Reason: (i) This prevents the undue expansion of the periodic table i.e., maintains its structure. (ii) This preserves the principle of classification by keeping elements with similar properties in a single column.
<h3>What is the difference between transition and inner transition elements?</h3>
The main difference between transition metals and inner transition metals is that transition metal atoms have their valence electrons in the outermost d orbital whereas inner transition metal atoms have their valence electrons in the f orbital of the inner penultimate electron shell.
<h3>How many inner transition elements are there?</h3>
Total number of inner transition elements in periodic table is 28, 14 each in lanthanoid and actinioid series.

Answer:Frequency (hz) is some sort of vibration occurs during a particular period of time as either in a sound waves or in an electromagnetic field. Given below an online frequency of light with wavelength calculator to convert from wavelength to hz. Wavelength (λ) is the distance between two waves of energy traveling from one point to another point.
Explanation:
Answer:
The ratio of the mass of an adult rhino to the mass of a small egret is
(1400 kg)/(0.76 kg) = 1842.11
The ratio of the mass of a proton to the mass of an electron is
1836.15
The two ratios are very similar, the ratio of the masses of the proton to the electron being slightly smaller.
<span>A 18 M solution of an acid that ionizes only slightly in solution would be termed
concentrated and weak. The concentration of the acid is high. The acid which dissociates partially in water is a weak acid.
</span><span>Calculate the [H^+] for the aqueous solution in which [OH^-] is 1 x10^-9. Is this solution acidic, basic or neutral. To determine [H+] use:
1x10^-14 = [OH-][H+]
solve for [H+]
[H+] = 1x10^-14/1x10^-9
= 1x10^-5</span>
