Chromium lose 6 or 3 electrons.
An ion forms when an atom with the same number of protons as electrons looses or gains one or more electrons. This gain or loss of electrons would be due to some sort of ionic bond
It will lose 2 to form Sr2+
Iodine tends to gain one electron when it forms an ion.
electrons are negatively charged, so losing electrons will result in a cation, or a positive ion.
it gains one electrons to form I- ion
None.Calcium loses 2 electrons to form an ion.
A non metal needs to GAIN electrons to form an ion
lose
A sulfur atom will gain two electrons to form a 2- sulfide ion.
Chromium lose 6 or 3 electrons.
Fluorine will gain one electron to form F- (or fluoride) ion. Fluoride ion has a charge of -1.
Selenium will gain two electrons and arsenic will gain three electrons
An ion forms when an atom with the same number of protons as electrons looses or gains one or more electrons. This gain or loss of electrons would be due to some sort of ionic bond
A nonmetal will gain one or more electrons in order to form a negatively charged ion.
No. In ionic bonds metals give away electrons.
gain one electron to form fluoride anion
