How are ions formed from atoms?
Ions are the formation of unbalanced atoms due to an attraction caused by a near completion of an electron ring in one atom and extra or valence electrons in the outer ring of another. If an atom gains an extra electron its over all charge is negative and the opposite is true for the atom gaining an electron.
Ions that are made of more than one atoms are examples of a.neutral ions b.positive ions c. negative ions d. polyatomic atoms?
Think about the question and each of the answers, particularly d) Polyatomic atoms. Even if I had no knowledge of chemistry, (d) would be the obvious answer. The question wants ions with MORE THAN ONE ATOM. Poly=Many/multiple, so 'polyatomic' quite literally means 'more than one atom'.
after atoms and molecules of gases and liquids are heated they move away from the heat . what takes their place?
ions
Do chemical bonds share atoms?
No. However, covalent bonds share electrons between two atoms. In an ionic bond, electrons are either gained or lost forming ions.
A crystal structure is characteristic of what?
atomic packing arrangements of ions, atoms etc. A crystal structure is a characteristic of a mineral.
Does gold have ions present in it?
gold, the metal, is made up of atoms. ions can form in gold only if there are suitable nonmetals to transfer the electrons to. metallic gold will not ionize spontaneously alone. gold can form +1 or +3 cations.
What form of atoms or molecules form ionic bonds?
Ions, charged atoms
Which atoms form ions most easily?
unstable atoms
Why do some atoms form positive ions and some form negative ions?
Because they want to.
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.
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.
Is sodium found in total cereal in the form of atoms or ions?
+1 ions.
Why do negative ions form?
Negative ions are formed when atoms accept electrons.
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
