Which element can form both positive and negative ions?
Hydrogen is the element that can form both positive (H+) and negative (H-) ions. When hydrogen gains an electron, it forms a negative ion, and when it loses an electron, it forms a positive ion.
Which transition represents a time when water molecules are moving closer together?
Frost forms on a window pane.
What is the majority of negative charge on the water molecule?
there has to be a negative charge in the molecule as there is a positive charge. there is a negative charge and when it and a positive charge gets together it forms something that makes the charge neutral
Does uranium have positive or negative ions?
Uranium can form both positive and negative ions, depending on the specific chemical conditions. In its most common form, uranium typically forms positive ions by losing electrons to achieve a stable configuration.
What atom can form a negative ion but usually forms a positive one?
Non Metals

What does a positive and a negative equal?
When dealing with multiplication, a positive and a negative number forms a negative answer.
Does chlorine form positive or negative ions?
Chlorine forms a negative ion.

What type of chemical forms between positive and negative ions?
Ionic bonds form between positive and negative ions.
Does Fe form negative ions?
No, it forms positive ions.
What type of chemical bond forms between negative and positive ion?
Ionic bonds form between positive and negative ions.
Why is frost on a car window a physical change?
Frost forming on a car window is a physical change because it is a reversible process where water vapor in the air solidifies into ice crystals when it comes into contact with the cold surface of the window. The chemical composition of the water molecules remains the same before and after the frost forms.
If frost forms on a window is it a physical chang or a chemical?
Physical- that is water vapor freezing into ice. It can be reversed (warm up the window) Chemical changes don't reverse.
