If it's outermost electron shell is filled.
If it's outermost electron shell is filled.
an atom that holds other atoms
Carbon
no, atoms don't have to have neutrons, neutrons are supposed to be neutral so it wont change the charge of the atom if you add or subtract neutrons from an atom. what will change is the mass number of the atom.
Atoms of elements have a fixed number of electrons that can bond with other atoms. Carbon has 4 electrons that can bond with other atoms. So 4 hydrogen atoms can bond with one carbon atom.
If it's outermost electron shell is filled.
No: A full valence shell means the atom is very stable and has little likelihood of combining with other atoms.
atom can not exists without protons. At least one proton is necessary to form an atom. For example hydrogen atom. It does not contain neutron. All other atoms has got neutrons also in the nucleus.
Yes, it is possible.
An oxide always has at least one oxygen atom as well as at least one atom of a different element.
Kevlar does.
When it's outer electron shell is full and it is in a cold (like near 0K) environment.
To be the central atom in a compound, the atom must be able to simultaneously bond to at least two other atoms. He, F, and H cannot serve as central atoms in a Lewis structure
no, atoms aren't alive. A microorganism has to be at least a bacterium, which are composed of many atoms.
an atom that holds other atoms
An oxide is a chemical compound containing at least one oxygen atom as well as at least one other element. Ex. Carbon Dioxide (One carbona atom, two [di] oxygen atoms).
An atoms size is relative to the number of electrons an atom contains. Atoms with the least number of electrons are the smallest atoms. When atoms have the same number of electrons, the atom with the most protons will have the largest nuclear charge, and therefore be the smallest atom.
