Will Ba gain or lose electrons?
To determine if Ba will gain or lose electrons, look at its position on the periodic table. Barium is in Group 2, so it typically loses 2 electrons to form a 2+ cation.
Which group of elements lose 2 valence electrons when their atoms form ionic bonds and what charge would the ions formed have?
elements of group 6 - colloum 10 gain 2 valence electrons when they form ionic bonds
Atoms of metals do what with electrons to become stable while atoms nonmetals tend to do what to electrons to become stable?
Choices: a) eject, retain B) lose, gain c) retain,gain d) gain, lose e) lose, retain
What atoms tend to gain two electrons to form a 2- anion?
se and sometimes gain electrons. Atoms with eight valence electrons do not easily lose electrons
Which group of elements lose 2 valence electrons when their atoms form ionic Bond?
Group 2
Are atoms of group 16 elements more likely to gain or lose electrons?
Atoms of group 16 elements are more likely to gain electrons because they have 6 valence electrons and need 2 more to achieve a stable octet configuration, which is typically done by gaining electrons rather than losing them.
Does group 2A elements lose or gain protons or electrons?
Group 2A elements tend to GAIN electrons!!
How many atoms does calcium lose?
I am not sure what you mean by atoms, i think you mean electrons (part of an atom).Calcium is in Group 2 of the periodic table so this means that in order to become stable it will lose 2 electrons.
What do atoms gain or lose when they bond?
If the chemical bond is ionic, an electron is gained or lost. If it is covalent, the electron is shared equally; if it is polar covalent, the electron is shared unequally. If the bond is intermolecular, no parts of the atom are actually shared, gained, or lost; the atom itself is simply attracted to other atoms.
When Barium and Oxygen react to form an ionic compound does Barium atoms lose 2 electrons and form a cation?
Yes, in the reaction between barium and oxygen to form an ionic compound, barium atoms will lose 2 electrons to form a Barium cation with a 2+ charge. Oxygen will gain those 2 electrons to form an oxide anion with a 2- charge.
Does group 2 on the periodic table gain or lose electrons?
they will lose electron to form mono positive cation
What is the r elationship of number of valence electrons of elements to their group in the periodic table?
Valence electrons are in the outer shell of the atom. The first column (group 1)has a +1 valence, which means that it has an extra electron it can 'lose' when bonding with other atoms. The 2nd column (group 2) has +2. The same goes for groups 3. Group 4 can gain 4 and lose 4. Group 5 can 'gain' 3 electrons, group 6 can gain 2 electrons etc.
