Ionic bonding is defined as the total transfer of valence electrons between atoms. What happens in ionic bonding is that a metal loses electrons to become a positive charged cation. On the other hand, the nonmetal receives those electrons to become a negatively charged anion. From the given choices above, the option that you would expect to form an ionic bond when combined is option A. Ca and O.
Water is a liquid
carbon is a solid
nitrous is a gas
Mole = mass / molar mass
123/138.6 = 0.8874
Mr=
K - 39.1
Cl- 35.5
O4 - (16x4= 64).
39.1+35.5+64 = 138.6
Answer:
The two elements with atomic number 9 and 12 are represented by letter Q and R respectively, where Q represents fluorine atom and R represents magnesium atom.
1. Electronic configuration of R that is magnesium (atomic number 12) is:
1s2 2s2 2p6 3s2
2. Q represents fluorine atom, which belongs to group 17 in periodic table that is the most reactive and lightest member of the group.
3. Q and R that is fluorine and magnesium combinely form magnesium fluoride or MgF2.
