In the following table, some elements have been arranged in a certain pattern:

sa (do)	re (re)	ga (mi)	ma (fa)	pa (so)	da (la)	ni (ti)
H	Li	Be	B	C	N	O
F	Na	Mg	Al	Si	P	S
Cl	K	Ca	Cr	Ti	Mn	Fe
Co and Ni	Cu	Zn	Y	In	As	Se
Br	Rb	Sr	Ce and La	Zr	-	-

Identify the periodic law with which the given table is associated. List two important features and two anomalies of the above periodic law.

Identification of the Periodic Law:

The given table is associated with Newlands' Law of Octaves.

Two Important Features:

1. Arrangement by Atomic Mass: Elements are arranged in the increasing order of their atomic masses.
2. Periodicity of Properties: It established that the properties of every eighth element are a repetition of the properties of the first element, similar to the octaves found in music (e.g., Lithium, $Li$, and Sodium, $Na$, have similar properties).

Two Anomalies (Limitations):

1. Applicability Limit: The law was applicable only up to Calcium ($Ca$). After calcium, every eighth element did not possess properties similar to those of the first.
2. Grouping of Dissimilar Elements: To fit the existing elements into his table, Newlands placed two elements in the same slot (e.g., Cobalt, $Co$, and Nickel, $Ni$) and placed them in the same column as halogens (Fluorine, $F$, Chlorine, $Cl$, Bromine, $Br$) which have completely different properties.
