The characteristc bright line spectrum of an atom is produced by

1.electrons absorbing quanta
2.electrons emitting quanta
3.protons absorbing quanta
4.protons emitting quanta

HI, there that answer will be (2.) Electrons emitting quanta.

Explanation:

well..Traits are basically your phenotype. They include things like hair color, height, and eye color. Alleles are versions of genes. ... This is a pretty basic idea of how traits and alleles are related...

Hope this helps you :)

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
