How does an ion with a charge of 2 form?
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
How many electrons must the oxygen atom lose to be stable?
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
What is the net charge of o?
An Oxygen atom has 8 protons and 8 electrons 1 Proton = +1 8 protons = +8 1 electron = -1 8 electrons = -8 Net charge = 0 Oxygen ion has 8 protons and 10 electrons 8 protons = +8 8 electrons = -10 Net charge = -2
If an atom loses 2 electrons when it forms an ion what is its ionic charge?
+2
What kind of charge will an atom have if it gains or loses one or more electrons?
If an atom loses an electron, it will be positively charged. An example may make this clearer. A neutral carbon atom has 6 protons and 6 electrons. If you take away an electron, you will have 6 protons and 5 electrons, for a total charge of +6 -5 = +1.
What charge does 2 electrons have?
2 unbalanced electrons have a 2- charge on the molecule/atom
What is the difference between an electrically charged atom or a electrically balanced atom?
Most atoms are electrically balanced because they have the same number of protons, which have a charge of +1, and electrons, which have a charge of -1. However electrons can be lost or gained. When they are, the atom has a different number of protons to electrons so it becomes charged. Example. An uncharged atom of oxygen has 8 protons and 8 electrons. Sometimes it gains two electrons. This means that it has 8 protons but 10 electrons. +8 -10 = -2. therefore the charged atom of oxygen has a charge of -2.
What charge would an oxygen atom with 10 electrons have?
An Oxygen atom would never contain 10 electrons on its own. It would have a maximum of 8 electrons at one time, unless the "oxygen atom" you are referring to is in fact an oxygen ION, in which case the charge would be -2. However, an oxygen ion can never be "by itself". It must be bonded with either itself as a diatomic or with another element as a compound.
An atom has 10 protons in its nucleus and 10 electrons in orbit around the nucleus Frictional forces temporarily srtip away two of the electrons The net charge on this atom is?
+10 + (-8) = +2+10 + (-8) = +2+10 + (-8) = +2+10 + (-8) = +2
When does an atom become an ion with a charge of 2 plus?
Barium has two electrons in its outermost shell, electrons carrying a negative charge. When the Barium atom becomes an ion, these two electrons are lost. Now the Barium atom has more protons than electrons, meaning a net positive charge of 2.
When an atom becomes a ion with a 2- charge the atom?
an ion with a 2- charge has 2 more electrons than usual
When an atom becomes an ion with a negative 2 charge the atom?
Gained 2 electrons
How does an ion with a charge of 2 form?
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
How does the balance of protons and electrons determone whether an atom is electrically charged?
If the number of protons is the same as the number of electrons, the atom is Neutral (the +'s and the -'s cancel out, leaving no net charge). If there are more electrons than protons, then the atom is negatively charged. If there are more protons than electrons, then the atom is positively charged. A Helium atom has 2 protons and 2 electrons: ++ --: No net charge: Neutral. A Chloride ion has 17 protons and 18 electrons: 17+ 18 -: Net charge -1: Negative (anion). A Sodium ion has 11 protons and 10 elections: 11+ 10-: Net charge +1: Positive (cation.
What describes what happens when an atom becomes an ion with a 2-charge?
An ion with a charge of 2- was an atom that lost 2 electrons to gain noble gas configuration.
What is the subatomic particles charges of calcium atom?
The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus.The protons have a positive charge, the neutrons have no charge, and the electrons have a negative charge.
What is the charge of an atom with twelve electrons and ten protons?
-2
