The way it both the atoms bond together is because of ionic bonding. Potassium has a charge of +1, while sulfur has a charge of -2. If you combine them, you would get:

However, it needs to neutralize and have a charge of 0 for it to bond successfully. This would result in having TWO potassium, so potassium would have a charge of +2, neutralizing with sulfur's -2 charge. Therefore, it needs 2 potassium that adds to a charge of +2, and therefore resulting to the formula K2S.

Because potassium sulfide is made of potassium and sulfur so for every 2 atoms of potassium you need 1 atom of sulfur

A(n) _____ is equivalent to an electron. gamma ray omega particle alpha particle beta particle

ladessa [460]

Answer:

beta particle

Explanation:

Alpha beta and gamma radiations are the examples of ionizing radiations. When an atom is an excited state and having high energy, the atom is in unstable state. The excess of energy is released by the atom to get the stability. The released energy is in the form of radiations which may include alpha, beta, gamma, X-ray etc.

¹⁴₆C → ¹⁴₇N + ⁰₋₁e

The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.

Beta radiations:

Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.

The mass of beta particle is smaller than the alpha particles.

They can travel in air in few meter distance.

These radiations can penetrate into the human skin.

The sheet of aluminium is used to block the beta radiations

Explain atoms contain positively charge protons and negatively charge electrons. why does an ordinary atom have no charge?

tatiyna

An ordinary atom is balanced for instance, lithium has 3 protons and 3 electrons the positively charged proton cancels the negatively charged electron.

THINK math plus 3 and negative 3 = 0 neutral
