How do you know which is more stable?

Rules for estimating stability of resonance structures
  1. The greater the number of covalent bonds, the greater the stability since more atoms will have complete octets.

What is stable and example?

firmly fixed or not likely to move or change: If the foundations of the house aren't stable, collapse is possible. After several part-time jobs, he's now got a stable job in a bank. The hospital said she was in a stable condition (= not likely to get worse) following the operation.... see details ›

What is the stable state?

A state or condition in which a system will remain unless or until it is disturbed by some outside force.... read more ›

Which is a stable atom?

A stable atom has a net charge of 0. In other words, it has an equal number of protons and electrons. The positive protons cancel out the negative electrons. When the number of electrons does not equal the number of protons, the atom is ionized.... read more ›
