Any number from 1 for Hydrogen to 118 for Ununoctium. It all depends on what atom you are looking at and how many protons exist within it. To be stable the number of electrons should equal the number of protons to create an overal charge of 0. Check your local Periodic Table such as the one provided in the links below.
What else can I help you with?
How many electrons does a stable sodium atom have?
Sodium has 11 electrons.
What causes an atom to be stable?
An atom becomes stable by gaining or loosing electrons.
How does a atom become stable?
When the atom has 8 valence electrons.
Atoms are more stable in their outer shell if they have?
A chemical stable atom is when it has the same number has electrons and protons. When the electrons and the protons are same it cannot react with any other atom till then and the atoms are called as inert atoms.
Bohr's model of the atom compares electrons to what?
Bohr's model of the atom compares electrons to planets orbiting around the sun. In the same way that planets have stable orbits around the sun, electrons have stable orbits around the nucleus of an atom.
How are electrons bound to the nucleus in an atom?
Electrons are bound to the nucleus in an atom through electromagnetic forces. The negatively charged electrons are attracted to the positively charged protons in the nucleus, creating a stable orbit around the nucleus.
What causes an atom to be stable and unstable?
An atom is stable when its nucleus has a balanced ratio of protons and neutrons, and when its electrons are in filled energy levels. An atom is unstable when it has an imbalance of protons and neutrons in the nucleus, leading to radioactive decay in an attempt to reach a more stable configuration.
How does the fact that electrons are negatively charged impact their behavior in an atom?
The negative charge of electrons affects their behavior in an atom by causing them to be attracted to the positively charged nucleus. This attraction keeps the electrons in orbit around the nucleus, creating stable electron configurations within the atom.
How is cl- ion formed by the cl atom?
The Cl atom gains an electron from another atom, and electrons carry a 1- charge. The Cl atom does this because it has 7 outer shell electrons, which isn't very stable, while an outer shell of 8 electrons is stable.
When an atom has eight valence electrons it has a stable arrangement called what?
stable electronic configuration
Is the chlorine atom stable?
Yes, the chlorine atom is stable. It has a full outer electron shell with 8 electrons, making it a highly reactive and stable element.
An atom does not need any electrons if it has outermost shell?
An atom needs electrons in its outermost shell to be stable. The number of electrons in the outer shell determines the atom's chemical properties and reactivity. If an atom's outer shell is complete, it is considered stable and less likely to react with other atoms.
