The charge is 2+.
The charge of a positive sodium ion is +1 C.
An Ion. An ion can have an overall positive or negative charge. The negative charge of an electron exactly cancels the positive charge of a proton, so when an atom has an equal number of both, it carries zero charge. An ion with more protons than electrons has a positive charge, and is more specifically termed a cation. An ion that has more electrons than protons, and therefore a negative overall charge, is called an anion.
The particles that affect the charge of an atom or ion are electrons and protons. Electrons have a negative charge and protons have a positive charge. The number of electrons and protons in an atom or ion determines its overall charge.
Any atom with 8 protons is an oxygen atom. Seven neutrons makes it a particular isotope of oxygen, and nine electrons means that it is an ion, with a charge of minus one. This is unusual because oxygen tends to form ions with a charge of minus two, not minus one, but it isn't impossible.
In an ion your protons do not change it will always stay the same. So in this case Lithium would hae three protons
A fluoride ion (F⁻) has gained an extra electron, giving it a -1 charge. Fluorine has an atomic number of 9, meaning it has 9 protons. Therefore, a fluoride ion has 9 protons and 10 electrons.
There are 19 protons in an ion with 18 electrons and a -1 charge. The -1 charge indicates that the ion has gained an extra electron, resulting in one more electron than protons.
This ion will have a charge of -1. The atomic number is the number of protons in the atom's nucleus. A neutral atom will have a number of electrons equal to the atomic number, which is the number of protons in that nucleus. Since you have an extra electron your atom has a negative charge of one electron's worth, or minus one, which is 1.6 x 10-19 coulombs.
Atomic number is the number of protons in the nucleus of an atom. Therefore, sodium's atomic number is always 11, even if it loses 1 electron. However, when a sodium atom loses 1 electron, it will form an ion with a 1+ charge.
A positively-charged ion or cation has more protons than electrons. The proton number is the atomic number of the element, while the electron number is the atomic number minus the charge. A negatively-charged ion or anion has more electrons than protons . Again, the number of protons is the atomic number. Positive ions are chemical species which carries a positive electrical charge. These ions form when an atom or molecule loses an electron. Therefore, Positive ions have more protons than electrons. But, negative ions are chemical species which carries a negative electrical charge. These ions form when an atom or molecule gains an electron.
when the chlorine atom gains an electron its charge becomes -1. this is because the total number of electrons for chlorine is now 18. protons and electrons have the same atomic number, but when a chlorine ion forms it has one extra electron compared to the number of protons therefore giving it a negative charge of 1.
The atomic core for a chloride ion consists of 17 protons in the nucleus, giving the ion a net charge of -1 to balance the single electron in its outer shell. This configuration gives it the same electron configuration as a noble gas (argon), making it stable.
There are 11 protons in an ion with 10 electrons and a -1 charge. The charge of an ion is defined by the difference between the number of protons and electrons. In this case, since the ion has a -1 charge, it means there is one more electron than the number of protons.
2-
The atomic core for a potassium ion is composed of 19 protons and usually 20 neutrons in the nucleus. This gives it an atomic number of 19 and a mass number of around 39. The potassium ion has a 1+ charge due to the loss of one electron.
+1
A sulfide ion has 16 protons and 18 electrons. The additional electron gives the ion a negative charge, making the number of electrons greater than the number of protons.
