francium , in the Periodic table the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. making helium is the smallest element, and francium the largest.
Explanation:
23 are the number of atoms
Answer:
Immiscible
Explanation:
Immiscible is the term that is used to refer to a mixture of liquids which can separate into distinct layers when left undisturbed. This usually comes to play when a polar solvent such as water is mixed with a non polar solvent such as kerosene.
These two liquids can be made to separate from each other using the method of separatory funnel
Electrons are shared in compound X and transferred in compound Y.
<h3>Further explanation </h3>
1. ionic bonding
Bonding that occurs due to electron transfer. Can occur in metal and non-metal atoms. To get stability, atoms release or bind electrons to get stable electron regulation from noble gases
2. covalent bonding
Bonding that occurs due to shared use of electron pairs
The two bound atoms contribute their electrons to produce bonds
Generally occurs in non-metallic elements
So compound X = covalent bond (metal with metal) and compound Y= ionic bond(metal with non metal)
- Compound X : shared electron
- Compund Y : transferred electron
