The total positive charge of the nucleus is cancelled by the negatively charged electrons revolving around the nucleus. Hence atoms are electrically neutral
Non-binary or polyatomic compounds are covalently bonded atoms with a net charge.
No. What you describe is called a molecule. An ion is an atom or group of atoms with a net electrical charge.
it would depend on amino acid in question. pH above amino acid pI, zwitterion will carry net negative (-) charge. at pH below pI, zwitterion will carry net positive (+) charge. depending on the amino acid, some have more than one acidic or basic functional group. such functional groups can make the amino acid vary in net charge from 2- to 2+ if not more.
Neutrons have no net charge. They are comprised of two down quarks, each with a charge of -1/3 and one up quark, with a charge of +2/3. These cancel out, for a net charge of zero.Constrast this with the proton, with one down quark, -1/3, and two up quarks, +2/3. for a net charge of +1.In 1932, English scientist James Chadwick discovered another particle in the nucleus of atoms. This newparticel, called neutron, was hard to detect because it has no electric charge.
Ionic compounds contain positive and negative ions, which bond together by electrostatic forces. The net charge is zero of a sample of an ionic compound.
No they do not.
Atoms are neutral in charge
Atoms are neutrally charged if they have equal numbers of protons and electrons. Technically speaking, all atoms have no net electrical charge - ions have a positive/negative charge.
No. The "n" and "p" does not refer to the negative or positive charge, but to the fact that there are atoms that can easily "donate" electrons (n-type), or atoms that can easily "accept" electrons (p-type).
True. The atoms have a proton which has a positive charge and there are same number of electrons with a negative charge. Those two charges cancel each other out and the charge becomes zero. The neutrons do not have any charge.
Atoms do not have any charge, if they have, they are called as ions.
Neutral atoms always have a net charge of 0(zero).
It is an ion.
Positive atoms: cations. Negative atoms: anions
H2O2 is a molecule known as hydrogen peroxide It has n net charge. 2OH- is two hydroxide ions, they are separate from one another and each carry a -1 charge.
Protons of an atom carry a positive charge. Electrons carry a negative charge. Neutrons carry no charge at all, but they are part of the atom.
