Atom is defined as the smallest part of an element which has chemical properties.It consist of a nucleus having combinations of neutrons and protons bound to the nucleus.
So Electrons cannot travel in definite circular pathways around the nucleus.
hence the right option is <span>C) Electrons travel in definite circular pathways around the nucleus</span>
<span>The pie is going to be hot right when it comes out of the oven because the oven uses air to transfer heat. The air warms at the bottom of the oven and the air rises to the top of the oven where your food is. This is why any food is going to be hot right after you take it out of an oven.</span>
Because it has high electrical conductivity
Hydrogen H weight: 81
Non-metal
Hydrogen is the simplest element; an atom consists of only one proton and one electron. It is also the most plentiful element in the universe. Despite its simplicity and abundance, hydrogen doesn't occur naturally as a gas on the Earth--it is always combined with other elements.

Hydrogen is easily the most abundant element in the universe. It is found in the sun and most of the stars, and the planet Jupiter is composed mostly of hydrogen. On Earth, hydrogen is found in the greatest quantities as water.
