<span>A) Frequency due to motion
As you are moving toward the object that is making the sound the frequency is higher. When you begin to move away the frequency lowers.

I think Both protons and neutrons (and their anti-particles) froze out at 1013 K, about 0.0001 seconds after the Big Bang. Protons and neutrons are sub atomic particles of an atom that are found in the nucleus of an atom. Proton is the positively charge particle while the neutron has no charge. The proton positive charge accounts for the positive nuclear charge.

Answer:
Group 1 and 2 elements
Explanation:
Nitrogen, a non-metal will form ionic bonds with most group 1 and group 2 metals on the periodic table.
How does ionic bonds form?
- They are bonds formed between a highly electronegative specie and one with very low electronegativity.
- As such, ionic bonds forms between metals and non-metals
- In this bond type, the metal due to its electropositive nature will transfer electrons to the non-metals for it to gain.
- The non-metals becomes negatively charged as the metal is positively charged.
- The electrostatic attraction between the two specie leads to the formation of ionic bonds.
Most metals in group 1 and 2 fits in this description. Some of them are calcium, magnesium, lithium, Barium e.t.c.
It mostly favors group 2 metals.
