How many electrons are in the outermost energy level of an oxygen atom as it shares electrons with hydrogen atoms as part of water molecule?
An oxygen atom has 6 electrons in its outermost energy level. When it shares electrons with two hydrogen atoms to form a water molecule, oxygen will share 2 of its electrons with each hydrogen atom, allowing each hydrogen to complete its outermost energy level with 2 electrons. This results in oxygen having a full outermost energy level with 8 electrons.
A combustion reaction occurs when a substance usually containing carbon reacts with what to produce energy in the form of heat and light?
oxygen
Why is O the element symbol for oxygen?
A lone oxygen atom has 6 outer shell or valence electrons but like other atoms, is most stable with a full outer shell of 8 electrons. In order to get this full outer shell, the oxygen atoms shares electrons with another atom, this is called a covalent bond. In the O2 molecule there are two oxygen atoms bonded together. Each atom contributes 2 electrons to be shared between both atoms, allowing each atom to achieve a full outer shell.
Why do bubbles form when you split up water?
Bubbles form when you split up water because the water molecules are composed of two hydrogen atoms and one oxygen atom. When the water is split, the hydrogen atoms combine to form hydrogen gas (H2), which bubbles up and separates from the oxygen atoms.
Why does complete combustion release more energy than incomplete combustion?
Complete combustion occurs when a fuel reacts with oxygen to form carbon dioxide and water, releasing more energy because all the fuel is efficiently converted into these products. In incomplete combustion, not all the fuel reacts to form carbon dioxide and water, leading to the release of less energy as other byproducts such as carbon monoxide or soot are formed.
When iron reacts with oxygen to form rust each iron atom.?
In that reaction, each iron atom loses three electrons.
When iron reacts with oxygen to form rust each iron atom losses or gains ions?
When iron reacts with oxygen to form rust, each iron atom loses electrons to oxygen to become oxidized. This results in the formation of iron ions (Fe^2+ or Fe^3+) which are then combined with oxygen atoms to form iron oxide, commonly known as rust.
What atom can form oxides peroxides and superoxides when it reacts with oxygen?
This element is sodium and the oxides are: Na2O, Na2O2, NaO2.
When iron reacts with oxygen to form rust each iron does what?
When iron reactions with oxygen to form rust, the iron atoms, Fe reacts with the oxygen atoms, O2 to create iron (III) oxide, Fe2O3.4Fe + 3O2 -----> 2Fe2O3Or2Fe + 3/2O2 -----> Fe2O3
How many atoms of carbon react with a molecule of oxygen to form a molecule of carbon monoxide?
there is one atom of oxygen in Carbon monoxide (CO) i.e. half molecule of oxygen.
When iron reacts with oxygen to form rust each iron atom losses or gains irons?
The iron atom doesn't gain or loss "irons". The question does not make sense.
When cesium reacts with oxygen to form an ionic compound each metal atom loses 2 electrons and each nonmetal atom gains?
In the reaction between cesium and oxygen, cesium (Cs) loses 1 electron to form Cs+ ions, while oxygen (O) gains 2 electrons to form O2- ions. This results in the formation of the ionic compound cesium oxide (Cs2O).
What is one atom of sulfur reacts with one molecule of oxygen to form one molecule of sulfur dioxide?
When one atom of sulfur reacts with one molecule of oxygen, they combine to form one molecule of sulfur dioxide. This reaction involves the sulfur atom bonding with the oxygen atom to create the sulfur dioxide molecule, which has one sulfur atom and two oxygen atoms.
What happens to the outer shell of a calcium atom when it reacts with an oxygen atom?
When a calcium atom reacts with an oxygen atom, the calcium atom loses two electrons from its outer shell and the oxygen atom gains those electrons. This forms a calcium ion with a 2+ charge and an oxygen ion with a 2- charge. These ions then bond together to form calcium oxide.
What happens when a molecule absorbs ultraviolet radiation?
When oxygen absorbs UV, it breaks it down. That atom then reacts again with oxygen to form ozone.
Does mangnesium and oxygen form an ionic bond?
Yes: Each magnesium atom transfers its two valence electrons to an oxygen atom to form the ionic compound magnesium oxide.
If the valency of Mn is 2 then how does it react with oxygen to form MnO2?
Manganese (Mn) has a valency of +2 in MnO2. It reacts with oxygen by combining one manganese atom with two oxygen atoms, forming manganese dioxide (MnO2). In this compound, each manganese atom is bonded to two oxygen atoms in a 1:2 ratio.
