Radium lose two electrons, the cation is Ra2+.
When atoms lose and gain electrons, an ionic bond will form. When atoms share electrons, a covalent bond will form.
To form a molecule, atoms can share, lose, and gain electrons
Ions do not share electrons with other atoms. Ions are formed when atoms gain or lose electrons to achieve a stable electron configuration. Positive ions (cations) lose electrons, while negative ions (anions) gain electrons.
Typically no because it is a noble gas and has a full octet.
This depends on the electronegativity of atoms.

To form a molecule, atoms can share, lose, and gain electrons
Some atoms lose electrons, some gain electrons, and some share electrons depending on what elements are involved and what compound is forming.
Ions do not share electrons with other atoms. Ions are formed when atoms gain or lose electrons to achieve a stable electron configuration. Positive ions (cations) lose electrons, while negative ions (anions) gain electrons.
Atoms that join by a covalent bond share electrons but do not gain or lose them. In a covalent bond, the electrons are shared between the atoms, creating a stable electron configuration for both atoms involved.
This depends on the electronegativity of atoms.
Typically no because it is a noble gas and has a full octet.
A completely filled shell of electrons has 8 electrons.
do atoms of a covalent bond lose r share electrons
Atoms share, gain, or lose electrons in order to achieve a stable configuration, usually a full valence shell. This is known as the octet rule. By doing so, atoms can attain lower energy levels and become more stable.
Krypton tends to neither lose nor gain electrons since it has a full outer electron shell, making it stable.
Xenon is a noble gas and typically does not react with other elements to gain, lose, or share electrons in chemical reactions. Its outer electron shell is already full, making it stable and unreactive.
