What has 9 protons and 10 neutrons?
fluorine atoms
Why can’t oxygen have 9 protons?
Oxygen is defined as “an atom having 8 protons in the nucleus.” Atoms having 9 protons in the nucleus are called “fluorine.” An oxygen atom has 8 protons in its nucleus. Why can’t it have 9 protons? Because an atom that has 9 protons would be Fluorine.
Why does oxygen only have 8 protons?
Oxygen’s 8 electrons are negatively charged, and they orbit the atomic nucleus and balance the positive charge of the 8 protons. The positive charge of 1 proton exactly cancels the negative charge of 1 electron. Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!
What happens if an atom loses a neutron?
Its mass is lowered, but it is still the same element. Its mass stays the same, and it is still the same element. Its mass is lowered, and it becomes a different element. …
What would be the name for Li+?
Lithium ion | Li+ – PubChem.
Does oxygen lose or gain electrons?
Similarly, when oxygen, O, gains 2 electrons the anion is O2–. The 2 represents the 2 gained electrons and the – is for the negative charge the oxygen gained.
Is N3 a cation or anion?
The ion that has the positive charge is called a cation, while the ion which has the negative charge on it is called as an anion….Comparison Chart.
| Basis for Comparison | Cation | Anion |
|---|---|---|
| Examples | Iron (Fe2+), Sodium (Na+), Lead (Pb2+). | Fluoride (F-), Bromide (Br-), Iodide (I-), Nitride (N3-) and Hydride (H-). |
What is difference between cation and anion explain with example?
Anions and cations are both ions….Difference Between Anions and Cations.
| Basis | Anions | Cations |
|---|---|---|
| Definition | An anion may be defined as an atom or molecule that is negatively charged. | A cation may be defined as an atom or molecule that is positively charged. |
| Charge Type | Negative | Positive |
| Type of Element | Non-Metal | Metal |
| Type of Electrode used | Anode | Cathode |
Is H an anion?
The hydrogen anion, H−, is a negative ion of hydrogen, that is, a hydrogen atom that has captured an extra electron. The hydrogen anion is an important constituent of the atmosphere of stars, such as the Sun. In chemistry, this ion is called hydride….Hydrogen anion.

Why is cation used before anion?
Demineralisation. For many applications, all ions in the water must be removed. The cation resin is usually located before the anion resin: otherwise if the water contains any hardness, it would precipitate in the alkaline environment created by the OH— form anion resin as Ca(OH)2 or CaCO3, which have low solubility.
Is water an anion or cation?
The positively charged ions are called cations, and the negatively charged ions are called anions. Because water is globally neutral electrically (otherwise you would get an electric shock when you put your hand in water) the number of positive charges is identical to the number of negative charges.
Is nacl a cation or anion?
In table salt, sodium chloride, sodium is the cation (Na+) and chloride is the anion (Cl-). In the crystal structure, the anion (Cl-) and the cation (Na+) form a regular pattern alternating back and forth.
What is the difference between cation and anion resin?
Anion resins and cation resins are the two most common resins used in the ion exchange process. The difference between anion and cation resins is that one is positively charged (anion) and the other is negatively charged (cation). cation resins, which attract positive ions with their negative charge.
What kind of resin is used in water softener?
polystyrene divinyl benzene
What is a cation vs anion?
An anion is an ion that has gained one or more electrons, acquiring a negative charge. A cation is an ion that has lost one or more electrons, gaining a positive charge.
Which resin is heavier cation or anion?
The anion resin is less dense than the cation resin; thus, it has a smaller exchange capacity, and a larger volume is needed for anion resins than for the cation resins to obtain equal total exchange capabilities.
Which is used to recharge anion exchange resin?
The resin can be recharged by washing it with a solution containing a high concentration of sodium ions (e.g. it has large amounts of common salt (NaCl) dissolved in it). The salt is used to recharge an ion-exchange resin, which itself is used to soften the water.
What is the pH range of weak cation exchange resin?
While strong base anion resins function throughout the entire pH range, weak base resins are limited to solutions below pH 7.
What is the process of DM water plant?
In two-bed demineralization, a stream is first treated with a strong acid cation (SAC) resin that captures the dissolved cations, and releases hydrogen (H+) ions in exchange. The resulting mineral acid solution is then routed to the strong base anion (SBA) resin bed.
What is DM or RO water?
Reverse Osmosis is often used to partially clean-up tap water before any other purification technology is used to remove the remaining 1-10% of contaminants. Deionization (DI) filters have many names: Ion Exchange, Strong Acid/Strong Base, Polishing, Nuclear Grade.
What is TDS of DM water?
Demineralized water is generally defined as having between 1-10 mg/L (ppm) of total dissolved solids (TDS). By contrast, spring or mineral waters have TDS levels of between 50-300 mg/L.
What is pH of DM water?
7.0
Can we drink DM water?
Demineralised water that has not been remineralized, or low-mineral content water – in the light of the absence or substantial lack of essential minerals in it – is not considered ideal drinking water, and therefore, its regular consumption may not be providing adequate levels of some beneficial nutrients.
Is 6.5 pH water bad?
Acidic water with a pH of less than 6.5 is more likely to be contaminated with pollutants, making it unsafe to drink. It can also corrode (dissolve) metal pipes.
How pure is deionized water?
Deionized (DI) water is commonly used in scientific applications where experiments using water can be counted on to be 100% pure, leading to more predictable and repeatable results. This type of water is also used in pharmaceutical applications for safety and consistency reasons.
