Given below are two statements:
Statement (I): An element in the extreme left of the periodic table forms acidic oxides.
Statement (II): Acid is formed during the reaction between water and oxide of a reactive element present in the extreme right of the periodic table.
In the light of the above statements, choose the correct answer from the options given below:
Step 1: Statement (I) is incorrect because elements on the extreme left of the periodic table, such as alkali metals and alkaline earth metals, form basic oxides, not acidic oxides.
Step 2: Statement (II) is correct because non-metals, which are on the extreme right of the periodic table, form acidic oxides when they react with water.
For example, sulfur dioxide (\( \text{SO}_2 \)) reacts with water to form sulfurous acid (\( H_2SO_3 \)).
Thus, the correct answer is that Statement I is false but Statement II is true.
Let \( A = \{-3, -2, -1, 0, 1, 2, 3\} \). A relation \( R \) is defined such that \( xRy \) if \( y = \max(x, 1) \). The number of elements required to make it reflexive is \( l \), the number of elements required to make it symmetric is \( m \), and the number of elements in the relation \( R \) is \( n \). Then the value of \( l + m + n \) is equal to:
For hydrogen-like species, which of the following graphs provides the most appropriate representation of \( E \) vs \( Z \) plot for a constant \( n \)?
[E : Energy of the stationary state, Z : atomic number, n = principal quantum number]
