Is helieum a gas?
Not only that, but it's one of lightest, or possibly the lightest, gas in the world. I'm a nerd, so you can trust me.
What is the simplest structure of life?
Many people might think the answer to this question would be an atom, but not in life. The structures go like this from largest to smallest: Ecosystem, Community, Organism, Organ system, Organ, Tissue, Cell.
Are atoms electrically charged particles?
An electron is a sub-atomic particle, not an atom. But it is electrically charged (it has a charge of minus one). The simplest atom, the hydrogen one isotope, has just one proton and one electron. An electron is a part of an atom. Every atom is composed of protons and electrons. Usually there are also neutrons. Protons are positively charged +1 and electrons are charged -1. Neutrons are neutral. When the number of protons and electrons are equal the atom is neutral. When an atom has an unequal number of protons and electrons it is charged either - or +. More electrons make it - and more protons make it +. In both cases the atom is called an ion.
Which is the smallest atom?
The smallest atom is hydrogen.
What are the two lightest gases in the universe?
In our known universe, hydrogen then helium. But this may change with further exploration.
Which atom is the lightest?
The lightest atom is hydrogen. It consists of a single proton and an electron, making it the simplest and lightest element on the periodic table.
Atom that has a nucleus with no neutrons?
An atom with a nucleus that has no neutrons is hydrogen-1, which consists of one proton and no neutrons. It is the simplest and lightest element on the periodic table.
What is the symbol for the lightest atom?
The lightest atom is hydrogen, and its symbol is H.
What is the definition of the word hydrogen?
Hydrogen is the lightest (it is a gas) and most abundant element in the Universe. A hydrogen atom consists of a single proton and a single electron, making it the simplest atom in the Universe.
Which is the lightest component of an atom?
electrons
The lightest of an atom's main constituents?
The lightest of an atom's main constituents is the electron. Electrons have a very small mass relative to protons and neutrons, and they orbit the nucleus of an atom.
What subatomic particles are the lightweights of the atom?
The lightest particle in the atom is the electron.
What chemical symbol does lightest atom have?
Hydrogen is the lightest chemical element; the chemical symbol is H.
What is the simplest organized substance known?
The simplest organized substance known is probably elemental hydrogen, with each atom consisting of just one proton and one electron. Hydrogen is the lightest and most abundant element in the universe.
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 have one proton and no neutrons in its nucleus?
An atom with one proton and no neutrons in its nucleus is a hydrogen-1 atom, also known as protium. It is the most common isotope of hydrogen and is the simplest and lightest chemical element.
What element is the lightest and simplest and abundant in the universe?
hydrogen
