There are electrons surrounding it and it is an electron cloud. Electron clouds are undfinable.
He has the smaller atomic size. Fluorine has the larger atomic size from these 3. He is a noble gas.
It is called a GAS. Gases have no definite volume (can be compressed) and no definite shape
atomic size decreases across a period
The atomic size increase from top to bottom of periodic table. As the number of shells increases from top to bottom, the atomic size increases.
Substances that assume the shape of their container but do not have a definite size is water or any liquid substance.
Earths atmosphere? 300 miles. There is no definite boundary.
The atomic radii is the measure of the size of the atoms in a chemical element. This is the distance from the nucleus to the boundary of the electrons' cloud.
A liquid has a definite size but no definite shape. In contrast, a solid has definite size and shape, and a gas has no definite size or shape.
The atomic radius, is the measured size of the atoms of a chemical element. Usually this is the typical distance between the nucleus and the boundary of the surrounding electrons.
The atomic radius of francium and caesium are considered to be equal.
A solid has both a definite size and shape. A liquid has a definite size but no definite shape. A gas has neither a definite size nor shape.
water
No, but it does have a definite volume.
the minimuim size
He has the smaller atomic size. Fluorine has the larger atomic size from these 3. He is a noble gas.
Solids have a definite shape and size. This is where solids differ from liquids and gases, for which the same cannot be said.
A gas has no definite shape or volume.
