Electrostatic forces between the positively charged nucleus and the electron.
In a covalent bond if there is a difference of electronegativity between the atoms then the shared electrons are "attracted" to the most electronegative element.
Electrical charge. However they can't fall in any further than "ground state" of innermost unfilled orbital because they are fermions and thus must all be in different states.
electrons
No electrons are "attached" to the nucleus of either atom. In a covalent bond one electron from each atom is shared with the other atom.
The particle that "circles" the center of an atom is an electron. (In reality, electrons act more like waves vibrating around an atom that particle circling an atom.) (Both neutrons and protons make up the center of an atom, neutrons have no charge and protons a positive one.)
The centre of an atom is called the nucleus, and it contains only protons and NEUTRONSbut no electrons at all.
Just remember that an atom has protons and electrons. Looking at an ionic bond at the molecular level, one atom takes electrons from the other atom. Now, one of the atoms has more electrons than the other. Look at the atom that lost electrons - it's missing a shell; there is less electron shielding, and a lot more places for the protons in the nucleus to attract electrons. Conveniently, the atom right next to this one has an abundance of electrons, and they are both attracted to each other. --> Think of the atom that lost electrons as positively charged, and the atom that gained electrons negatively charged.
electrons
Nucleus is at the center of atom. It is surrounded by electrons.
Electrons are negatively charge and are attracted to the positively charged Protons in the nucleus of the atom

electrons are negitively charged, they are attracted to positive charge. Either a proton or positively charged atom.
In an atom, the electrons spin around the center, also called the nucleus.
They do get attracted, but their momentum is too high to be "captured" by the electrons.
The nucleus is the center of an atom. The protons and neutrons are inside the nucleus. The electrons are outside the nucleus.
Electrons
The center of an atom is the nucleus. Inside an atom you will find neutrons, electrons and protons. The nucleus is the most important part of an atom.
the atom may not be stable
Neutrons and electrons are found in the nucleus of an atom; electrons are outside the nucleus in "electron clouds".
