Answer:
A compound is a unique substance that forms when two or more elements combine chemically. Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds. A chemical bond is a force of attraction between atoms or ions that share or transfer valence electrons
Its has 24 protons, 24 electrons, and 28 nuetrons
It is likely the neutral atom has 6 protons and 6 electrons; while the negatively charged atom has 7 or more electrons.
The mass of an atom, commonly known as the atomic mass is determined by the number of protons and neutrons as electrons have a very low mass.
This means two atoms can have the same number of protons and neutrons, but a different number of electrons, which would make the atom be charged negatively or positively.
Based on this, if there are two atoms, each with 6 protons but one of these is negatively charged it is because the second atom has 1 or more extra.
Neutral atom:
- This atom has 6 protons and an unknown number of neutrons located in the nucleus.
- This atom has 6 electrons that orbit the nucleus.
- The first energetic level will include 2 electrons while the second energetic level will include the 4 remaining electrons.
Negatively-charged atom:
- This atom has 6 protons and an unknown number of neutrons located in the nucleus.
- This atom has 7 or even more electrons that orbit the nucleus.
- The first energetic level will include 2 electrons while the second energetic level will include up to 8 electrons.

Atomic number. The atomic number is determined by the amount of protons in the nucleus.
After ion exchange with zeolite in water filter to remove calcium by substitute natrium ion with calcium ion, the weight of zeolite become 1.9578 kg.
ion exchange calculation can be done by using basic stoichiometry if we know how the reaction of the ion exchange. In this case where zeolite with natrium ion will be exchanged with calcium. The reaction of exchange will be like this:
⇒ 
Calculate the molecule weight of both zeolite
Atomic weight data:
Na = 23 gram/mole
Si = 28 gram/mole
Al = 27 gram/mole
O = 16 gram/mole
Ca = 40 gram/mole
Molecule weight
= 142 gram/mole
= 278 gram/mole
Calculate mole from 2kg of zeolite with natrium :
2000 gram/ 142 = 14.0845 mole
Based on the stoichiometry, we got the mole of zeolite with calcium:
14.0845 mole x 1/2 = 7.0423 mole
Weight of zeolite after the ion exchanged with calcium:
7.0423 mole x 278 = 1957.8 gram = 1.9578 kg
