<span>These values also increase from the
bottom to the top of a group because the size of the atom decreases, resulting
in a smaller distance between the nucleus and the valence electron shell, which
increases the attraction between the protons and electrons.</span>
Answer:
So combining blue with yellow light is like combining blue light with red and green light. The result of combining these three primary colors of light is to produce white light.
Explanation:
Answer:
Transfer of heat between two objects that are touching.
Explanation:
Conduction is the process by which heat is transferred from one object to another object that is touching and has different temperatures.
Eg: We can use a hot water pack to warm our back. Or While cooking we can feel the conduction process when heat process from the bottom of the pan to the top of the pan
Answer:
C.5
Explanation:
A number of electrons present in valence shell of penultimate Shell represents the group of elements.
For s block elements: no.of group=number of valence shell electron.
p block elements: no. of group= 2 + 10 + number of valence electrons.
d block elements: no. of group= number(n-1)d electrons + number of electrons in nth shell.
Here, the differential electron is in p orbital hence, it belongs to p block
No. of group= 2+ 10 + 3=15 i.e 15th group or VA group.
