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:

Concepts Used:
Anomalous Behaviour of Beryllium
- Anomalous behavior of an element mentions the deviation of the properties and behavior of an element from its usual or normal behavior.
- Beryllium has a small atomic size as well as ionic size.
- The high ionization enthalpy and small size of alkaline earth metals reverberate in the formation of covalent compounds that are easy to hydrolyze.
- Their coordination number is not greater than 4 due to the presence of 4 electrons in the valence shell.
- Their oxide and hydroxide are amphoteric in nature.
