It is a matter of how full an atom's outer or valence shell of electrons is. For most atoms, the most stable setup is one with a full shell of 8 valence electrons, and an atom will gain or lose electrons to achieve this. For atoms with close to 8 valence electrons, such a chlorine (7 valence electrons, it is generally easier to gain electrons and thus become negatively charged. For atoms with few valence electrons, such as sodium (1 valence electron), it is easier to lose electrons and go down to the next lowest shell, which is already full.
What else can I help you with?
Will atoms of a non metallic element form positive or negative ions?
Positive ions
Why do some atoms form positive ions and some form negative ions?
Because they want to.
How many covalent bonds will form between two atoms with one with a negative and positive charge and the other with a negative and positive charge?
1
Is arsenic positive negative or neutral?
Arsenic atoms are neutral and they form ions with valency of three.
How do positive and negative ions forms?
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
What are the properties of an atom that determine its interaction with other atoms based on the presence of positive and negative charges?
The properties of an atom that determine its interaction with other atoms based on the presence of positive and negative charges are its atomic number, electron configuration, and the distribution of positive and negative charges within the atom. These factors influence how atoms bond with each other to form molecules.
Do ionic bonds form between ionized atoms?
Yes, only if there are both ions with positive charges and ions with negative charges among the ionized atoms.
Do non metal elements only form positive ions?
Metals tend to form positive ions also known as cations.
Atoms gain or lose electrons to form ions?
They can do both to form ions. An ion simply means that there is an uneven distribution of charge, so it can be positive or negative.
Can isotopes have positive and negative charges?
Isotopes are just the different possible nuclear weights of each element. Some are stable; some are unstable and radioactive. Since all atoms are isotopes and all isotopes are atoms, Isotopes can - and do - form ions, consequently they can have positive and negative charges.
What does rubidium form a positive of a negative?
Positive
When Ca combines what ion does it form?
In an ionic bond to other atoms: Ca+2 , a positive ion (cation).And negative ions (anions) of the the combined atom or group of atoms.
