Answer:

Flame color is dependent on temperature.

Explanation:

Scientists have learned from various experiments which shows that red flames occurs when the temperature reaches to 980º up to 1,800º Fahrenheit. The colour of flames turn orange when the temperature reaches to 2,000º up to 2,200º Fahrenheit and when the temperature approaches 2,400º to 2,700º Fahrenheit, flames colour turns white.

1. Which out of the following elements has the lowest electronegativity: Lithium, Beryllium, Magnesium, Sodium
lidiya [134]
  1. The element Sodium (Na) has a low electronegativity of the following elements.
  2. The element Beryllium (Be) has the least metallic character.
  3. The element Sodium (Na) has the largest atom.

<u>Explanation:</u>

  • Sodium (Na) which is a delicate, shimmering white, profoundly responsive soluble base metal loses an electron to a chlorine iota since it has seven electrons in its valence shell.
  • It needs one more electron to turn into a steady molecule. It has the most reduced electronegativity of the given components.
  • Beryllium (Be) is a light, silver-gray, relatively soft metal that is strong but brittle has the least metallic character of the given elements.
  • Since from left to right in a period, Metallic character decreases while nonmetallic character increases from top to bottom.
  • Sodium(Na) is the largest atom among the given elements since Atomic size decreases across a period from left to right and increases from top to bottom.
