The charge is 2+.
2+
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.
No. That would be called an ion.
This occurs because the absolute value of the positive charge of the protons, which are concentrated in the nucleus of the atom, is offset by the negative charge of the electrons also in the atom but more diffusely located outside the nucleus. The absolute values of the charge on a proton and the charge on an electron are equal, but the charge on protons is positive and that on electrons is negative. If an atomic size entity contains no electrons, it is not an atom but a positive ion.
Atoms consist of three subatomic Particles (Nuetrons, Protons, and electrons) when an atom looses an electron which is negatively charged it makes that atom positive, when an atom looses a Proton it makes it negative since that proton had a postive charge it is no longer balanced between negative and postive subatomic particles
For a neutral atom they must have equal numbers of protons and electrons. The atomic number is the number of protons in an atom of an element. Find the atomic number by looking at the periodic table of elements.
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.
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.
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.
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.

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-.
Protons, neutrons and electrons
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.
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.
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)
An electron has a negative charge. Also an ion in which there are more electrons than protons has a negative charge. Such an ion is called as anion.
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.
