ionic bond
The nitrogen atom forms 3 covalent bonds.
0. One side is positive, one is negative
It is due to the hydrogen bonds holding water molecules together. Hydrogen bonds are the weekest bonds because they are the slight attraction between a positive and a negative charge.The reason water molecules have a positive and negative charge is because they are polar- the electrons of H2O are shared unevenly in their covalent bonds. A water molecule is held together with polar covalent bonds. Water molecules are held together by hydrogen bonds.
Ionic bonds are chemical bonds by positive ionic charge(normally hydrogen , metals +) and negative ionic charge(chlorine ,sulphur etc ) that bind to form compounds.
potassium is an alkali metal with a charge of +1. It will bond with anything with a negative charge. With the elements, they want to form perfect bonds. That is, a neutral charge of 0. So the greater the negative charge, the more potassium atoms that can be bonded to it.
Yes phospate bonds have a negative charge.
1
just put true
The charge is 0 if the positive and negative charges were equal
Ionic Bonds form between positive cations, and negative anions and has an electronegativity of greater then 1.7. All ionic bonds are therefor formed between a metal and non-metal.
The nitrogen atom forms 3 covalent bonds.
one end of the molecule has a slightly negative charge and the other a slightly positive charge.
A polyatomic ion is held together by covalent bonds between atoms. They can be either positive or negative. For example, the ammonium ion, NH4+, has a positive charge, and the sulfate ion, SO42-, has a negative charge.
covalent bonds: relatively low melting point, bond is not as strong as ionic, form between two nonmetals, valence electrons are shared between the atoms. ionic: relatively high melting point, stronger bond than covalent, form between a metal and nonmetal, valence electrons are transferred from the metal to the nonmetal, leaving the metal with a positive charge and the nonmetal with a negative charge. these charged particles are called ions. positive ion=cation, negative ion=anion.
because it has a negative charge
0. One side is positive, one is negative
