Let us consider that a new element has been found. It has an atomic structure in such a way that it could only be placed on the s- block of the periodic table.Where can it be placed ,then? Will they form a new period?? Send me your suggestions, please

Thank you very much . i was struggling to understand this fact for a long time.now you cleared my doubt.

We all know that gravitational force is an attractive force. In that case Earth should have been attracted towards the sun,isn't.Instead it revolves round the sun in a specific orbit.Why??

sorry i was busy at that time. thats why i typed wrongly.

Oxygen is the most abundant element ,isn't? But its percentage in the atmosphere(21%) is less than that of Nitrogen(78%) Then why nitrogen is not considered the most abundant element

Is Proxima centauri our nearest star?? My book says it is Alpha centauri

I have read that Universe will go on expanding(Big Bang Theory).At one stage the expansion stops and the universe will shrink again(Big Crunch theory).Is it true ???

I viewed a small chip using an electron microscope.I saw many crystal shaped structures in that small chip. My Physics teacher told me that those crystal shaped structures are metals(active and inactive). Is it true???

I have heard that leukimia(Blood cancer) increases white blood cells(I don't know the type).White blood cells are meant for defence mechanism isn't.Then why is it bad????

I read that by going through a warm hole, we can go to future ,is it true??

I want to know the exact velocity with which the Earth is revolving around the Sun. I tried out a simple experiment.The shadow of a wall goes on increasing during sunset(Evening), isn't it. I took a small scale and measured the distance travelled by the shadow of that wall in 1 min(from a particular point to another point)So i calculated the speed with which the shadow was moving, which ultimately means the speed with which the earth revolves around the sun

I have got an idea about making man to fly around. As Neil Armstrong said one can jump very high in the moon. That is because , the gravity in the moon is 1/6 that of Earth. Let us consider the gravity in the Earth to be 1. If we can increase the gravity by 5 or 6 and practise there ,we might be able to fly(jump very high) about in the Earth. I want some suggestions about my post.Reply me.
