How does a permanent magnet loses its magnetism?

It can lose it by being heated, being struck or being exposed to a rapidly changing magnetic field.


How many valence electrons will barium gain or lose to fill its outer shell?

It will lose 2 electrons.


Barium BA is in Group 2 Recall that atoms in Group 1 lose one electron to form ions with a 1 charge What type of ion does barium probably form?

barium will lose two electrons to form an ion with a plus 2 charge. Thus, the resulting ion in reactions of barium is Ba2+.Read more: http://wiki.answers.com/What_type_of_ion_would_barium_form_if_group_1_loses_one_electron_to_form_ions_with_a_1_plus_charge#ixzz17vdoXVSf


How many electrons do barium need to lose to become stable?

Barium, with an atomic number of 56, needs to lose 2 electrons to achieve a stable electron configuration, similar to a noble gas. This is because barium will then have a filled outer electron shell, following the octet rule.


How many electrons will barium need to gain or lose to make 8?

Barium has 56 electrons. To make 8 electrons, it would need to lose 48 electrons to reach a stable electron configuration similar to a noble gas.

How does salt lose its saltiness?

Sodium chloride can't lose his saltiness.


How many electrons does barium lose to become a stable octect?

Two electrons.


Is Barium unlikely to form positively charged ions?

Barium is highly likely to form positively charged ions because it is a metal in Group 2 of the periodic table, which tends to lose two electrons to achieve a stable electron configuration. This results in the formation of Ba2+ ions when barium atoms lose two electrons.


What will happen when barium and oxygen brought together in a chemical reaction?

When barium and oxygen are brought together in a chemical reaction, they will likely form barium oxide (BaO). Barium will tend to lose its two valence electrons, while oxygen will tend to gain two electrons to form a stable compound.
