The pull of one atom is slightly stronger,or weaker than the pull of the other atom.
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.
the positive and negative charges in clouds are the protons and electrons formed from the friction of the water that condensated to make the cloud.
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)
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.
Fluorine typically forms a negative ion with a charge of -1. This is because it has a high electronegativity, meaning it has a strong tendency to gain an electron to achieve a stable electron configuration.
When the difference of the electronegativity between the atoms is significant the molecule is less or more polar.
H2O is a polar covalent molecule. It forms covalent bonds between the hydrogen and oxygen atoms, but due to the unequal sharing of electrons, the oxygen atom becomes slightly negative while the hydrogen atoms become slightly positive, leading to a polar molecule.
The pull of one atom is slightly stronger,or weaker than the pull of the other atom.
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.
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.
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.
Negative times negative equals 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 positive.
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.
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.
This depends on the number of electrons lost or gained. Also important is the electronegativity of a specific atom.
