Answer : Option C) Atomic Size
Explanation : The atomic radius of the elements is found to be decreasing if we go from left to right in the modern periodic table. Accordingly,
increases as the number of shielding electrons present in the atomic nucleus of the periodic elements which lies in the same row remains constant while the number of protons in each atomic shell increases.
The effective nuclear charge
of an atom is defined as the net positive charge which is felt by the valence electron of the atomic element.
When
is observed to decrease, it is seen that the atomic radius grows in size. So, it explains the inverse relationship between both. This phenomenon occurs, because there is more screening of the electrons from the nucleus taking place, which is observed due to decrease the attraction between the electron and the nucleus.
Answer: There are five signs of chemical change
- Color Change
- Production of an odor
- Change of Temperature
- Evolution of Gas (bubbles start to form)
- Precipitate (starts to form a solid)
When these signs start to form you know chemical change is at work.
Hope this helps :)
Answer:
The correct answer would be - lose their native habitats are forced to migrate into new areas in search of shelter and food.
Explanation:
The removal of trees or deforestation to build a housing or city planning or development impact the birds and other animals of that area. Cutting most of the trees from the area will result in a decrease in available food, shelter, and breeding habitat.
It causes complete removal of bird species and forced them to migrate to a new place in search of places that will provide a source of shelter and food for birds.
