How many subatomic particles in potassium oxide?
Potassium oxide is K2O.It has 46 protons and 46 electrons (19 + 19 + 8 = 46).If the most stable isotope of K and O are used (K-39 and O-16), then there will be 48 neutrons (20 + 20 + 8 = 48).So the total number of sub atomic particles will be 140(46 protons + 46 electrons + 48 neutrons).
What is the pH OF beryllium oxide?
The PH of Beryllium Oxide is anything less than 6
Is hematite rare?
No, Hematite is basically iron oxide in a mineral state, rust is another state of iron oxide. It can be polished to a luster resembling the look of steel
In what form does oxygen occur in the Earth's crust?
Oxide
What are the pollution effects of non-metal oxides?
pollution effects of non-metal oxides are simple. i would teach you to answer your own question. firstly ask yourself what are non metal oxides? then when u find your answer, apply it to your question.so a nonmetallic oxide is compound composed of oxide ion and non-metal ion for example sulphur oxide, carbon dioxide, nitrogen oxide, hydrogen peroxide. now ask yourself what is pollution of sulphur oxide? answer= any contamination that enters this compound is known as polution. it will therefore make your solution or anything that the chemical is being used for wrong or slightly unprecise.
If an element has 8 protons and 8 neutrons in its nucleus and 8 electrons revolving around the nucleus What is the atomic number and atomic mass of this element?
In neutral atoms (with the same number of protons and electrons), the number of protons and electrons equal the atomic number. If our atom has 9 electrons, is neutral, and therefore has 9 protons, it is element #9: Flourine, which has an atomic mass of 19: 9 protons plus 10 neutrons.
How many protons are in the ion O2?
The neutrons and protons in the nucleus do not change when electrons are removed from an atom. Even when two electrons are removed. Oxygen has several isotopes, with 8 protons and either 8, 9, or 10 neutrons... all representing stable isotopes. 8 neutrons is most common on Earth.
What is the element that has 13 protons?
The number of neutrons is irrelevant for determining the element. 13 protons makes it aluminum. (The isotope of aluminum with 13 neutrons is unstable and radioactive, with a half-life of about 720,000 years.)
How many protons are in an oxide ion?
An oxide ion has 8 protons. This is because it is an oxygen atom that has gained 2 electrons to become negatively charged. The number of protons remains the same as the number of protons in a neutral oxygen atom.
How many protons does nitrous oxide have?
Nitrous oxide is N2O and has 22 protons (7 from each nitrogen, 8 from oxygen)
How many electrons are in a -2 anion that has 8 protons and 8 neutrons?
A -2 anion indicates that the ion has gained two extra electrons. Since there are 8 protons in the nucleus (8 electrons in a neutral atom), adding two extra electrons would give a total of 10 electrons in the anion.
How many subatomic particles in potassium oxide?
Potassium oxide is K2O.It has 46 protons and 46 electrons (19 + 19 + 8 = 46).If the most stable isotope of K and O are used (K-39 and O-16), then there will be 48 neutrons (20 + 20 + 8 = 48).So the total number of sub atomic particles will be 140(46 protons + 46 electrons + 48 neutrons).
An oxide ion formed from an oxygen -18 atom contains exactly how many protons neutrons and electrons?
The isotope oxygen-18 has the mass number of 18. The atomic number of oxygen is 8, so all of its atoms, regardless of isotope, have 8 protons. In a neutral oxygen atom the number of protons equals the number of electrons, so it has 8 electrons. The number of neutrons equals the mass number minus the atomic number, which for oxygen-18 is (18 - 8), so there are 10 neutrons.
What compound contains 15 protons?
Nitrogen (II) oxide, or NO contains one nitrogen atom (Z=7) and one oxygen atom (Z=8), for a total of 15 protons.
What element has 8 proton 8 neutrons and 10 electrons?
The element that has 9 protons is fluorine. Its atomic number is 9, indicating that the element has 9 protons in the nuclei of its atoms. If there are 10 electrons, then the fluorine atom has gained an electron and is now a negatively charged anion with a charge of 1-.
How many neutrons does a molecule of tin IV oxide contain?
A molecule of tin(IV) oxide (SnO2) contains 2 tin atoms (with 50 neutrons each) and 4 oxygen atoms (with 8 neutrons each). Therefore, the total number of neutrons in a molecule of tin(IV) oxide would be 2 tin atoms x 50 neutrons + 4 oxygen atoms x 8 neutrons = 116 neutrons.
How many protons does an oxide ion have?
8 proton
