How many protons and electrons are in oxygen?
8
Is the number of nucleons equal to the number of electrons?
The atomic number gives the number of protons in the atom. The number of nucleons gives the total number of protons plus neutrons in the atom. Since an atom is electrically neutral, an atom has always the same number of electrons (negative charge) and protons (positive charge).
How many electrons are in an oxygen atom?
2, 6
Why is oxygen the most important element?
Oxygen is an important element that is needed by most life forms on Earth to survive. It is the third most abundant element in the universe and the most abundant element in the human body. Oxygen has 8 electrons and 8 protons. The oxygen cycle plays an important role in life on Earth.
How is oxygen different from other elements?
Oxygen, because of the small size of its atom, the small number of electrons in its underlying shell, and the large number of protons in the nucleus relative to the atomic radius, has properties uniquely different from those of sulfur and the remaining chalcogens.
Which element does not react with water?
Metals like aluminium, iron and zinc do not react either with cold or hot water. But they react with steam to form the metal oxide and hydrogen. Metals such as lead, copper, silver and gold do not react with water at all.
Why is Ozone more reactive than oxygen?
Why ozone is more reactive than oxygen? Oxygen is more stable than ozone. on heating ozone readily dissociate and form oxygen and free radical of oxygen known as nascent oxygen which take part in reaction, thus ozone is more ractive than oxygen.
Does silver react with oxygen?
Chemical properties Silver is a very inactive metal. It does not react with oxygen in the air under normal circumstances. It does react slowly with sulfur compounds in the air, however. The product of this reaction is silver sulfide (Ag 2 S), a black compound.
