It is called "standard condition".
Certainly neutrons.
Hydrogen is the smallest atom by mass. Helium, neon, fluorine and oxygen are smaller in size. Many calculations put the helium as the smallest atom. But a few other calculations put neon as the smallest atom!
Is the healthy
Mainly empty space, with a very small and dense nucleus at the center containing the majority of the atom's mass.
All knowledge about the universe from the atom to the cell to the person to the earth to the sun to the farthest reaches of existence.
For a sp3-hybridized atom to display asymmetry, it must have four different groups attached to it.
No, the word "atom" should not be capitalized unless it is at the beginning of a sentence or part of a proper noun.
When calculating the mass of an atom, you add the mass of the protons and the neutrons. This is the nucleus of the atom. The electrons are small enough to be ignored except in the most delicate calculations.
An electron reaches zero energy when it is at rest or in a state of lowest energy level, typically in an atom's ground state.
no. of protons+no. of nuetrons in an atom is known as mass no. of that atom.while no . of protons present in an atom is called its atomic no.thus, in 1st condition we consider both, no. of protons as well as no. of nuetrons and in the 2nd condition we just consider no. of protons.
No.
