<h3>Answer </h3>

Potassium nitride= K3N

<h3>Explanation </h3>

Potassium nitride is the correct name of the compound with chemical formula, K3N. The compound is formed between potassium ion (K+) and nitride ion (N-3).

Potassium has nineteen electrons and since it obeys octet rule with electronic configuration of 1s2 2s2 2p6 3s2 3p6 4s1. Potassium loses an electron in its outer subshell(4s) to attain a stable electronic configuration (1s2 2s2 2p6 3s2 3p6). Thus, forming K+.

On the other hand, N has seven electrons with electronic configuration of 1s2 2s2 2p3. Nitrogen also obeys octet rule. Hence, it acquires three electrons to attain a stable octet noble gas configuration (1s2 2s2 2p6), resulting in N-3.

Every nitrogen atom acquires three electrons from potassium. Also, potassium loses one electron to each nitrogen atom. In this interaction every nitrogen atom becomes N-3 and each potassium becomes K+.

<span>You need to consider the valences of the two elements. Potassium is +1; nitrogen is -3. To balance the molecule, you need 3 potassium to one nitrogen, or K3N</span>

topjm [15]

Explanation:

Helium is produced in radioactive process that occurs in deep and underground formations. They differ from other atmospheric gases. These radioactive decay of heavier nuclides that are unstable started about the time when the earth was formed.

  • As they decay they give off lighter particles that can easily be broken down into more stable ones.
  • One of the main product of the decay is alpha particles.
  • They have the same atomic structure as helium
  • These materials are trapped in underground formations.

What number of atoms does K2CO3 have?
k0ka [10]
K2CO3 can be thought to contain 6 atoms (2 K, 1 C, 3O). 

If you are given grams of K2CO3 you can divide by the molar mass to get to moles and then multiply by Avogadro's number.

nadya68 [22]
M(NaCl) = Ar(Na) + Ar(Cl) · g/mol.
M(NaCl) = 22,99 + 35,45 · g/mol.
M(NaCl) = 58,44 g/mol.
V(NaCl) = 3,5 L.
m(NaCl) = 90 g.
n(NaCl) = m(NaCl) ÷ M(NaCl).
n(NaCl) = 90 g ÷ 58,44 g/mol.
n(NaCl) = 1,54 mol.
c(NaCl) = n(NaCl) ÷ V(NaCl).
c(NaCl) = 1,54 mol ÷ 3,5 L.
c(NaCl) = 0,44 mol/l = 0,44 M.
