Which of the parts of an atom is the lightest part of the atom why?
Depends, but it is probably electron
What subatomic particle has the less mass?
In the atom the electron is the lightest.
What subatomic particle Has the smallest relative mass?
In the atom the electron is the lightest.
What is the actual mass of an atom?
That depends on the atom you are refering to. Hydrogen is the lightest, heavy metals like uranium are a few hundred times heavyer.
What is the minimum amount of valence electrons an atom can have?
To answer this, we simply need to consider the lightest of the chemical elements, hydrogen. Hydrogen's atomic number, and thus its number of protons and electrons, is 1. So, by necessity, that is the minimum amount of valence electrons an atom can have.
What atom is the lightest and the simplest atom?
hydrogen
What is the symbol for the lightest atom?
Hydrogen is the lightest and most common atom in the universe. It has the symbol H and an atomic number of 1.
Which is the lightest component of an atom?
electrons
What subatomic particles are the lightweights of the atom?
The lightest particle in the atom is the electron.
The lightest of an atom's main constituents?
An atom is composed of three main particles, the proton, electron and neutron. The electron is the lightest among the three.
What chemical symbol does lightest atom have?
Hydrogen is the lightest chemical element; the chemical symbol is H.
Which of the parts of an atom is the lightest part of the atom why?
Depends, but it is probably electron
Which subatomic particles has the lest mass?
In the atom the electron is the lightest.
Of the three particles that make up an atom which is the lightest?
The electron.
What subatomic particle has the less mass?
In the atom the electron is the lightest.
What atom is the lightest?
The lightest and smallest atom is hydrogen. It has a single proton and a single electron. There are some other isotopes of hydrogen that have one or more neutrons. Although those isotopes are naturally occurring, they are rare and for most purposes, we can ignore their existence.
What subatomic particle Has the smallest relative mass?
In the atom the electron is the lightest.
