Answer:
A flame is defined as the gaseous part of the fire which is visible to us. A flame is created due to the high exothermic reaction.
Two types of flames based on the amount of oxygen available are:
- Non-luminous or blue flame: In this type of flame the amount of oxygen is sufficiently large and it gives blue flame. For example: flame of Gas stove.
- Luminous flame: In this type of flame, the oxygen availability id not sufficient for the complete combustion and left unburnt carbon particles that forms yellow light flame. For example: kerosene lamp.
The answer is sodium
Sodium has 11 protons (atomic number is 11) and has one valence electron. As the Bohr model diagram below shows, Sodium has 11 protons and 12 neutrons<span> in the nucleus to make the mass number 23. The 11 electrons necessary to make Sodium neutral (protons = electrons) are arranged in a pattern of 2-8-1.</span>
Elements are used to create bonds and are classified as particles.
