Two electrons are donated by Barium to an oxidant (nonmetal, eg. O2) by which barium gets oxidised.
Ba --> Ba2+ + 2e-This is because Ba is in group 2 of the periodic system, belonging to the 'earth alkali' metals and so it has 2 electrons (2e-) in its valency (or outer) shell (2,8,18,18,8,2). Hence Ba2+ configuration is (2,8,18,18,8,-), with an empty (-) 6th shell (the 'P' shell) like Xenon.Barium is in group 2, so it has 2 valence electrons. Hence, barium has to release two electrons to achieve the noble-gas configuration.
Barium loses 2 electrons to reach noble gas electron configuration giving it a +2 charge and the electron configuration of Xenon.
Boron will tend to lose three electrons to achieve noble gas configuration of helium.
Barium should lose 2 electrons to attain the electronic configuration of xenon
Two- to form Ba2+ with the Xenon electronic configuration.
Barium is in the 2nd group of the Periodic Table. It has 2 valence electrons. It gains noble gas configuration by removing 2 electrons.

Barium has 56 eletrons56 electrons and protons.
A neutral barium atom has 56 electrons.
A neutral barium atom has 56 electrons.

Barium has 56 eletrons56 electrons and protons.
A neutral barium atom has 56 electrons.
A neutral barium atom has 56 electrons.
A barium atom has two valence electrons.
The barium atom (neutral) contain 56 electrons.
Barium's atomic number is 56. Thus, an atom of barium has 56 protons in it. To keep it electrically neutral then, a barium atom must also have 56 electrons per atom.
No. An ion is a positively or negatively charged atom, or group of atoms due to more or less electrons than necassary. Both barium and sulfate are ions, but together they are a compound, not an ion. Barium Sulfate is a chemical compound made up of two ions, a barium ion and a sulfate ion. A Barium ion is Ba+2, meaning it has two less electrons that a barium atom has. The reason for this is because the barium atom has 56 total electrons. Every atom wants to be ion with a filled valence shell, that is to have the same or similar electronic configuration of a noble gas (the elements in the right most column). The valence shell is the outermost shell of electrons and for barium the other shell is 8 electrons. In order for Barium to do this, it has to somehow lose 2 electrons to become similar to Xenon's electronic configuration. Sulfate, SO4 -2, is also an ion. the -2 means it has aqcuired 2 more electrons from another ion. It got those two electrons from the barium atom, simultaneously making the barium atom a barium ion. Sulfate is called a polyatomic ion, meaning an ion made up of more than 1 atom. When the barium ion gives the sulfate ion two electrons, thus making both electronic configurations "happy" they bond together to make an ionic bond, creating the compound barium sulfate.
There are 2 valence electrons in Barium.
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.
The arrangement of the electrons in an atom is known as its electron configuration.

The configuration of an atom shows the arrangement of electrons, and also if the charge is positive or negative.
