How many electrons does oxygen have?
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 element has 8 protons?
Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons! What element contains 8 protons in its nucleus? Oxygen
How many protons electrons and neutrons does a carbon atom have?
An atom of carbon has six protons, six electrons, and six neutrons. What is the atomic mass of the carbon atom? Which statement describes atomic mass? a. The atomic mass of an atom is the same as the atom's atomic number.
Does the nucleus of an atom contain protons and neutrons?
Experiments by various scientists have shown that the nucleus of an atom contains protons and neutrons. The only exception is hydrogen, which has only protons in its nucleus but no neutrons. Electrons revolve around the nucleus in a specific orbit.
What is the charge of an oxygen atom that has 8 electrons?
A neutral oxygen atom will also have eight electrons. In an oxygen ion with a 2− charge, the number of protons is still 8, but the number of electrons is 10. This results in the oxygen ion having an octet (8) of valence electrons.
What is the charge of an ion that has 8 protons and 9 electrons what element is this?
An oxygen atom with 9 electrons (the nucleus has 8 protons) is symbolized O - . An oxygen atom with 10 electrons is symbolized O 2- , and an oxygen atom with 11 electrons is symbolized O 3- .
What is the charge of an oxygen O atom that has 8 protons and 10 electrons?
-2Protons are positive, so the nucleus has a +8 charge. Electrons are negative, so they have a -10 charge. We can determine the overall charge on the ion by simply adding +8 and -10. So, the oxygen ion has a charge of -2.
What is the charge of an ion if it has a protons and 9 electrons?
A fluorine atom has nine protons and nine electrons, so it is electrically neutral.
What element has 8 electrons and 9 neutrons?
Answer: The isotope of oxygen has 8 protons (p) , 9 neutrons (n) and 8 electrons (e-).
How do I calculate the charge of an ion?
Number of protons - number of electrons = charge on ion.
Why is the charge of oxygen negative 2?
The element oxygen has six valence electrons. To fill up the valence shell the oxygen atom needs two more electrons. As every electron has a single negative charge, adding two more electrons gives oxygen ion a charge of 2 .
What is the charge of an ion that has 8 protons 9 neutrons and 10 electrons?
With eight protons, we are necessarily looking at oxygen, but with 10 electrons, the net charge on the ion is minus two.
What does a +2 charge mean?
+2 charge indicates that any compound, molecule, or atom loses two electrons and becomes a cationic species. -2 charge indicates that any compound, molecule, or atom loses two electrons and becomes an anionic species. The example of a +2 charge is as follows: Barium , Cadmium , Lead , etc.
Which ion has a charge of 2 +?
Roman numeral notation indicates charge of ion when element commonly forms more than one ion. For example, iron(II) has a 2+ charge; iron(III) a 3+ charge.
What is the charge for 8 protons 10 neutrons and 8 electrons?
I.e., since an oxygen atom normally has 8 protons and 8 electrons, this ion has 10 electrons (-10 charge) and 8 protons (+8 charge) giving it a charge of -2 (-10 + 8 = -2).
What is the total charge of oxygen?
zeroWe have one, two, three, four, five, six, so there are six valence electrons around the oxygen in our drawing, so six minus six is equal to zero, so the formal charge on oxygen is equal to zero.
What element has 8 protons and 9 neutrons?
Because protons and neutrons are roughly equal in mass, an isotope's number is equal to the sum of its protons and neutrons. Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and oxygen 18 has 8 protons and 10 neutrons.
What is the charge of an ion that has 8 protons 9 neutrons and 10 electrons?
With eight protons, we are necessarily looking at oxygen, but with 10 electrons, the net charge on the ion is minus two.

What particle has 8 protons 8 electrons and 9 neutrons?
This is not on the periodic table. Isotopic notation includes the atomic number and the mass number. 8 17 This isotope of oxygen has 8 protons (atomic number), 8 electrons and 9 neutrons.
