No, not always. Some can exist in what's called a "monatomic state". That is, they exist as a single atom, either due to artificial separation from other atoms, or because they have no need to bond to other atoms.
Atoms tend to bond to other atoms to become more stable, but atoms that are already stable tend not to bond. Examples of such are the noble gasses, which rarely bond except through synthesis.
Yes. Atoms depend on other atoms to become stable.
No, they're made up of protons, neutrons, and electrons.
A sigma bond is the bond in which two atoms share the electrons.
If two bromine atoms form a bond with each other, the bond is covalent, not metallic.
Polar bond apex :)
It will be a non polar molecule because, electron's ARE shared equally in a bond. Atoms have same or similar EN(electronegativity) values.
With itself, and other elements.
In any diatomic element it is always a covalent bond.
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.
yes
A sigma bond is the bond in which two atoms share the electrons.
Atoms combine with other atoms to form compound. It makes the atoms stable.
covalent bond
when they are in contact
If two bromine atoms form a bond with each other, the bond is covalent, not metallic.
Cations donate atoms to form an ionic bond.
Cations donate atoms to form an ionic bond.
They can bond with 4 other atoms.
