An ion is an atom or molecule which has lost or gained one or more electrons, giving it a positive or negative electrical charge. A negatively charged ion, which has more electrons in its electron shells than it has protons in its nuclei, is called an anion(Greek meaning Up) , a positively-charged ion, which has fewer electrons than protons, is called a cation (Greek meaning down)
What else can I help you with?
What form of atoms or molecules form ionic bonds?
Ions, charged atoms
Which atoms form ions most easily?
unstable atoms
WHAT happens when sodium atoms react with iodine atoms to produce sodium iodine?
When sodium atoms react with iodine atoms, they undergo a redox reaction to form sodium iodide. Sodium atoms lose an electron to form Na+ ions, while iodine atoms gain an electron to form I- ions. These ions then combine to form sodium iodide crystals.
Why do some atoms form positive ions and some form negative ions?
Because they want to.
Can atoms lose or gain atoms to form elements?
No. Atoms of an element lose or gain electrons to form ions.
What do atoms become to form compounds?
ions
Negative ions form when atoms-blank-valence electrons?
Negative ions form when atoms GAIN valence electrons.
Why do negative ions form?
Negative ions are formed when atoms accept electrons.
Is sodium found in total cereal in the form of atoms or ions?
+1 ions.
Positive ions form when?
Positive ions (or cations) are formed when atoms lose electrons
Will atoms of a non metallic element form positive or negative ions?
Positive ions
In a covalent compound atoms form ions?
In a covalent compound, atoms do not form ions. Instead, they share electrons to achieve a stable electron configuration. This sharing of electrons creates a bond between the atoms in the compound.
