What is the charge of a positive sodium ion?
A positive sodium ion has a charge of +1, as it has lost one electron. Sodium normally has 11 protons and 11 electrons, so when it loses one electron it becomes a sodium ion with a charge of +1.
When an atom has different amounts of protons and electrons it is called an?
When an atom has different amounts of protons and electrons, it is called an ion. Ions can be positively charged (if they have more protons than electrons) or negatively charged (if they have more electrons than protons).
Which ion has eight protons in the nucleus and nine electrons in its orbits?
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.
Protons in a lithium ion?
A lithium ion has 3 protons. The number of protons in an atom determines its atomic number, which in turn identifies the element. So, lithium, with 3 protons, has an atomic number of 3.
How many electrons are in the uni-positive ion of sodium?
There are less electrons than protons in a positive ion. More information is needed to determine the exact number. Here is an example: How many electrons are in a carbon ion with a positive charge of positive 2e? There are 6 protons in carbon (since it is element number 6). Since it has a charge of +2, there will be 2 less electrons than protons, so the number of electrons would be 4.
How do you find the number of electron domains in an atom or ion?
This is based upon the number of protons in the atom's [or ion's] nucleus: it's atomic number. Protons possess one positive charge, normally balanced or offset by the negative charge possessed by an electron.
What happens to the atomic number of sodium when it loses one electron?
The atomic number of an element represents the number of protons in its nucleus. When sodium loses one electron, it forms a positively charged ion (Na+), but the number of protons in its nucleus remains the same. Therefore, the atomic number of sodium does not change when it loses one electron.
Does ion have neutral 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.
What is the charge of an ion that contains 21 protons and 19 electrons?
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.
What is the charge on a carbonate ion Compare to the number of protons how many electron does the carbonate ion have?
2-
What determines size of an atom?
Protons, neutrons and electrons
What is the total number of protons in the nucleus of an F- ion?
An F- ion has 9 protons in its nucleus. The element fluorine in its neutral state has 9 protons, but since the ion has a negative charge, it has gained one electron, resulting in a net charge of -1.
When a chlorine atom gains an electron what is it charge?
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.
How many protons are in a ion with 86 electrons and a -1 charge?
A neutral atom has an equal number of protons and electrons. Protons are positively charged, and electrons are negatively charged. Therefore if you have an ion with a -1 charge, it has one extra electron. So your ion has 85 protons.
Which ion has 17 protons 18 neutrons 18 electrons?
The ion with 17 protons, 18 neutrons, and 18 electrons is the chlorine ion, Cl^- (chloride ion). It has gained an extra electron to achieve a stable electron configuration.
What has 35 protons 45 neutrons and 36 electron?
Since it has 35 protons, it's atomic number is 35, which is the atomic number of Bromine. Bromine has an average Atomic Mass of 79.9 which would account for the 45 neutrons. Normally the number of electrons and protons are the same. Since there are 36 electrons that means there is one extra electron beyond the 35 protons. This means that the Bromine atom has gained an electron and is no longer electrically neutral. It is an ion with a charge of negative one (-1)
Fluorine has an atomic number of 9 What is the symbol and charge for an ion of fluorine that has 10 electrons?
A fluorine ion with atomic number 9 and 10 electrons has a charge of -1 because it has one extra electron as compared to the number of protons (10-9 = 1). Its symbol is F-.
