Answer:
Ionic size increases from top to bottom within the group.
Explanation:
- Ions are formed when neutral atoms of elements gain or lose electron(s).
- The ionic radius is the distance from the nucleus of an ion to the outermost energy level.
- The ionic size or radius increases down the group as the number of energy level increases.
- Therefore, an ion of an element lower in the group will be larger than the ion of an element higher in the group.
- For example, an ion of potassium, K+, is larger in size compared to the ion of sodium, Na+ since K+ has more energy levels than Na+.
Conductor = Radiator , Frying pan , Ceramic baking dish
Insulator = Winter coat , Oven mitt and ice chest
Answer:
FALSE
nuetrons do indeed have no charge, however they are nearly 2000 more times massive than electrons.
The strongest intermolecular forces are in ion-ion bonds which happen when a metal bonds to another metal. 2. The next strongest forces are ion-dipole bonds which happen when metals bond to nonmetals. 3.
Remember that carbon has 4 electrons in its valence shell meanwhile bromine has 7
So i think the lewis structure would be :
Br
C Br Br
Br
Hope this helps
