How do potassium chloride particles bond to water particles?
Potassium chloride is an ionic compound, composed of positive potassium ions and negative chloride ions. When it dissolves in water, the ions separate and become surrounded by water molecules. Water is a covalent compound, but it is polar, which means that one end (the oxygen) is a little bit negative, and the other is a little bit positive. The slightly negative ends are attracted to the positive potassium ions and the slightly positive ends are attracted to the chloride ions. These are electrostatic attractions.
Does fluorine form a positive or negative ion?
Negative (Fl-) All the halogens become negative ions.
Are hydrogen bonds strong or weak?
a hydrogen bond is a type of weak chemical bond. It is formed between the slightly positively charged hydrogen atom of one molecule and a slightly negative charged atom of another. A strong would be a covalent bond (it forms when atoms share electrons in order to become more stable)
A compound that consists of positive and negative ions?
The positive ion and negative ion before they are ions they were neutral atom. Then when the metals loses electrons it's protons (which is positively charged) will become more then electrons (which is negatively charge), so it become positive ion, but where it loses it's electrons? The answer is that it gives it's useless electrons to nonmetals were it is useful there and then the non metal changes into negative ion due to having electrons more than protons.
In ionic compounds what are the sum of the charges of all the cations and anions?
The positive and negative charges are equal in magnitude (absolute value).
How do some atoms in covalent bonds become slighty positive or slightly negative?
When the difference of the electronegativity between the atoms is significant the molecule is less or more polar.
How do some atoms in covalent bonds become slightly negative or slightly?
The pull of one atom is slightly stronger,or weaker than the pull of the other atom.

What occurs when there is an unequal sharing of electrons between atoms?
Part of the Molecule will be slightly negative and the other slightly positive. One example is water. The oxygen atom hogs the electrons leaving the oxygen slightly negative and the hydrogen slightly positive. This makes the water molecules slightly "sticky" and the water molecules clump together. If this didn't happen then water would boil at -120 deg C intead of +100 degrees.
When two atoms are sharing electrons in a covalent bond what will happen to the electrons when one of the atoms is more electronegative than the other?
Electronegativity= the ability of an atom to attract a pair of electrons in a covalent bondSo the electrons will be drawn towards the more electronegative atom, causing this atom to become slightly negative (δ-) and the less electronegative atom to become slightly positive (δ+), so the bond is polarised.
what is polar covalent compounds?
A polar covalent compound is a compound consisting of molecules which have regions of positive and negative charge due to the covalent bonding between atoms. The atom with a greater charged nucleus ( atoms with greater proton number) will attract the shared electrons causing them to move closer to the nucleus which will make this slightly negatively charged due to the negative electrons. The atom which the shared electrons has moved away from ( atoms with smaller proton number) will become slightly positively charged.
When multiplying negative integers does it become negative or positive?
Negative times negative equals positive.
Is a negative subtract a negative a positive?
Yes. A negative subtracted by a negative is a positive. Just remember that two like signs become a positive sign, and two unlike signs become a negative sign.
When we lose something negative you become?
When we lose something negative you become positive.
When you lose something positive you become?
When you lose something positive you become negative.
How do you change a negative number into a decimal?
You divide the negative number by a positive number for it to stay positive. And you divide the negative number by a negative number for it to become positive.
Why multiplication of negative numbers equals positive?
When you multiply any number by a negative number you reverse its sign. So positive numbers become negative, and negative numbers become positive. That is the meaning of negative multiplication; it is reversal. This is similar to the way that adding a negative number has the same effect as subtracting a positive number. Negative is the opposite of positive.
