an ion with a 2- charge has 2 more electrons than usual
Gained 2 electrons
When an atom becomes an ion with a 2+ charge, it means that the atom has lost two electrons, resulting in more protons than electrons. This gives the ion a positive charge since protons are positively charged particles. The ion will now be attracted to other particles with a negative charge to achieve stability through the formation of ionic bonds.
An ion with a charge of 2- was an atom that lost 2 electrons to gain noble gas configuration.
It becomes this ion after the gain of two electrons.
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.
Depends on how many electrons it gains. For every electron it gains, the atom becomes more negative. One electron gives it a -1 charge, 2 a -2 charge and so on
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
Electrically Charged or Negatively charged
It becomes a sulfur ion with a charge of -2.
When a sodium atom forms an ion, it loses one electron from its outer shell. This loss of an electron leaves the sodium atom with a positive charge, as it now has one more proton than electrons. This results in the formation of a sodium ion, specifically a sodium cation with a charge of +1.
it neets to loose 2 electrons to have a full outer shell.
An atom of sulfur-36 can gain two electrons to become a sulfide ion with a -2 charge. When it gains these two electrons, it achieves a stable electron configuration, similar to the noble gas configuration of argon, resulting in a charge of -2.
