Two sodium atoms are needed to provide the 2 electrons necessary to complete the valence octet of an oxygen atom. Sodium typically loses one electron to achieve a stable electron configuration, which can then be transferred to an oxygen atom to satisfy its electron needs.
the same number of electrons needed to fill their octet, the same number of valence electrons,
The Lewis diagram for fluorine (F) shows a single F atom with seven dots surrounding it, representing its seven valence electrons. These electrons are paired up in a single bond with another F atom, which creates a stable F2 molecule.
Six valence electrons in their outermost shell.
For most atoms, 8 valence electrons are needed to fill an octet when forming chemical bonds. This typically involves sharing, gaining, or losing electrons to achieve a full outer shell of electrons.
Two fluorine atoms are needed to form an ionic bond with calcium, as each fluorine atom will contribute one electron to satisfy calcium's two valence electrons.

Fluorine needs 8 valence electrons to have a filled outer energy level, following the octet rule. Fluorine naturally has 7 valence electrons, so it only requires one more electron to achieve a stable octet configuration.
Fluorine has 9 electrons to match its atomic number.
For OF2, oxygen (O) has 6 electrons, and fluorine (F) has 9 electrons each. Therefore, the total number of electrons needed to form OF2 is 6 (from oxygen) + 2 x 9 (from two fluorine atoms) = 24 electrons.
Two sodium atoms are needed to provide the 2 electrons necessary to complete the valence octet of an oxygen atom. Sodium typically loses one electron to achieve a stable electron configuration, which can then be transferred to an oxygen atom to satisfy its electron needs.
To form an ionic bond, calcium (which has 2 valence electrons) can donate its two electrons to sulfur (which requires 2 additional electrons to complete its valence shell). Therefore, one calcium atom can bond with one sulfur atom to form an ionic compound. Thus, only one calcium atom is needed to form an ionic bond with one sulfur atom.
the same number of electrons needed to fill their octet, the same number of valence electrons,
It depends on the atom. List what element the atom is from.
One chlorine atom is needed to form an ionic bond with one magnesium atom because magnesium can donate its two valence electrons to chlorine, which requires one more electron to complete its octet.
