Your information is inconsistant: Either this is a normal O16 with only 6 electrons in the outer shell, or this is a negative oxygen ion. Go with choice #1.
this guy must have missed the 2 electrons in the first shell, it can't be a normal O16 atom because there are more electrons than protons, so it is a negative ion
Everywhere! Matter as we know it, is generally made up of atoms. They are the building blocks of molecules. Inside an atom however, the protons, neutrons and electrons are located in different places. The proton, which is positively charged is found alongside the neutrons, with no charge, in the nucleus of the atom. The electrons then orbit the nucleus in shells. The first shell can hold up to two electrons, the second up to eight etc.
Oxygen atoms in water molecules are the same as oxygen atoms in any other molecules; the definition of an oxygen atom is that it is an atom which has eight protons in its nucleus. Normally it has eight neutrons and eight electrons as well, but that can vary. It is only the eight protons which define it as oxygen.
http://www.answers.com/topic/atomic-orbital Atomic orbitals are cloud like structures around the nucleus of an atom that contain the atoms electrons. There are s, p, d, and f orbitals. S contain up to 2 electrons, P contain up to 6 electrons, d contain up to 10 electrons, and f contain up to 14 electrons. These orbitals have electrons containing different amounts of energy, and it is possible for electrons to jump to and from different orbitals. When this happen energy either needs to be added or released. The number of orbitals present in an atom is completely dependent on the number of electrons present in the atom.
Each atom has orbitals where the electrons hang out. (in the center of the nucleus are the protons and neutrons) this keeps the atom itself stable by balancing the electrons to its protons. as you may know, each element has a different atomic number, which coincides with the number of electrons in its entirety. with exception to the very first orbit, each orbit can hold a maximum of eight electrons. when one orbit fills up, then the next will begin to fill, then so on and so forth. So, in an attempt at acquiring stability, the atom will try its hardest to fill its outermost shell by bonding and sharing electrons with other elements. The OCTET rule emphasizes on the re activeness of any given element based on the number of electrons already in its outermost shell. the closer a shell is to being full, the easier it is for it to be filled. thus for it is more likely to form bonds (more reactive), if the octet is already almost full. Octet stems from Latin meaning eight. hence the eight place holders in the outermost shells. There are also S shells, P shells, and D shells, which are said to orbit within one another and fill up in a specific chronological order. But I'll let someone else scare you with those fun facts. :)
Each element has a specific number of protons in the nuclei of its atoms. This number is known as the atomic number for the element. For instance, the atomic number of hydrogen is one because it has a just one proton in its nucleus. The atomic number of oxygen is eight, again because it has eight protons in its nucleus. For a full summary see the link for the periodic table.
Neon
Oxygen-16 has 8 electrons and 8 neutrons.
An atom is the basic unit of matter consisting of a nucleus (protons and neutrons) surrounded by electrons. Two examples of atoms are hydrogen, which has one proton and one electron, and oxygen, which has eight protons, eight neutrons, and eight electrons.
Neutrons and protons make up the nucleus; therefore, they cannot revolve around the nucleus. Electrons, on the other hand, are on orbitals surrounding the nucleus. The number of orbitals and the number of electrons per orbital depend on the placement of the element on the periodic table, the atomic mass, the atomic number, etc. A maximum of eight electrons can be on one orbital.
A particle diagram for a carbon-oxygen molecule would show two separate atoms, one representing carbon and the other representing oxygen. The carbon atom would have six protons and six neutrons in its nucleus, with six electrons orbiting around it. The oxygen atom would have eight protons and eight neutrons in its nucleus, with eight electrons orbiting around it.
In an Oxygen Atom there are two rings on which the Electrons orbit around the Nucleus, there is the inner ring and the outer ring. The inner ring closest to the Nucleus contains two Electrons and on the outer ring there are six Electrons making a total of eight Electrons, which is equal to the amount of Neutrons and Protons in the Nucleus (8 Neutrons, 8 Protons). This should answer the Question.
You put the number of protons and neutrons in the middle of the first circle (nucleus). The number of protons and electrons is the Atomic number. Round the atomic mass and subtract it by the number of protons and you have your neutrons. Draw another circle (shell) around the first one. You can only put up to two electrons in the first one. The next two circles you draw can hold up to 8. The last shell can hold 18. EG: Neon There are ten protons, neutrons and electrons. Draw the nucleus first, then write the number of protons and neutrons inside. Draw a shell around the nucleus and place two electrons side by side. Draw another shell around the first one and draw eight electrons around it.
The atomic mass of the element with eight protons and nine neutrons is 17 atomic mass units. This is calculated by adding the number of protons and neutrons together, as electrons contribute negligible mass to the overall atomic mass.
You need to know the atomic number to find the element, and the atomic number equals the # of protons and electrons, which is 6. It is Carbon.
The atomic number of oxygen is 8 because oxygen has 8 protons in its nucleus.The atomic number of a chemical element (also known as its proton number) is always the number of protons found in the nucleus of an atom of that element, and identical to the charge number of the nucleus. It is conventionally represented by the symbol Z.The Atomic Number is a count of how many Protons are present in an atom of an element.The element Oxygen has 8 Protons in its atomic nucleus and therefore has an Atomic Number of 8.Note: in an electrically neutral atom the number of electrons in the electron cloud exactly matches the number of Protons in the nucleus of the atom, therefore electrically neutral oxygen will also have 8 electrons.
For finding the atomic mass of any element, we have to get sum of number of protons & number of neutrons. Atomic Mass (A) : p+n. * p = no. of protons. * n = no. of neutrons. Therefore, atomic mass of oxygen is 15.
A negative 2 charge means that the oxygen is richer in two electrons. The configuration of oxygen is: 1s22s22p4 and we can conclude that it has 8 electrons. For the atom to be neutral the amount of protons must be the same. Oxygen atom has 8 neutrons. Let's add the two electrons to the eight, so the oxygen will be on negative 2 charge. To summarize, the amount of electrons - 10, protons- 8, neutrons - 8.
