Charges repel each other?
____________ charges repel each other.like
How is static electricity made?
=Usually, atoms have the same number of electrons and protons. Then the atom has no charge, it is "neutral." But if you rub things together, electrons can move from one atom to another. Some atoms get extra electrons. They have a negative charge. Other atoms lose electrons. They have a positive charge. When charges are separated like this, it is called static electricity.=
Why like charges repel and unlike charges attract each other?
The reason why some charges repel while unlike charges attract comes down to polarity. According to Newton, with every action there is an equal and opposite reaction. The reason comes down the the amount of protons and electrons in each atom. Equal amounts produce a repelling action where as charges with unequal protons and elections will cause the atoms to attract.
What are Dalton points in the atomic theory?
daltons atomic postulations stated that: * Elements are made of tiny particles called atoms. * All atoms of a given element are identical. * The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights. * Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms. * Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
Does whether or not charges will move in a material depend partly on how tightly they are held in the atoms of the material?
It depends on whether the charges are free to move. There are two ways in which charge can move through a substance. Ionic substances are made of positive and negative ions. In a solid they have fixed positions, but in liquids and gases they can move around. Ions are atoms (or groups of atoms) which have gained or lost electrons. How tightly their electrons are held has no effect here as it's the whole ion which moves. The second situation where charges can move is when electrons are in delocalized bonds. In most substances the electrons are in orbitals associated with one atom or a small group of atoms. In metals, some electrons are in large orbitals which are shared by all the atoms, so the electrons (which are charged) can move freely through the whole metal. In this situation, the delocalized electrons can be thought of as not held by individual atoms, but they are still held by the assemblage of atoms. So the assertion in the question has elements of being right, but it's not the degree to which the electrons are held, but whether or not they are delocalized.
What are their respective charges of a atom?
Electrically charged atoms are called ions: positive charge - cations, negative charge - anions.
Their respective charges are?
Positive, negative, neutral
Which atoms have a larger electronegativitey?
The halogens are most electronegative atoms in their respective periods.
Atoms have a higher number of positive charges than negative charges?
Cations, positively charged atoms e.g. Na+. The positive charges are the protons min the nucleus and the negative charges are electrons.
What are the two electric charges?
There are two types of charges: positive charges and negative charges. Positive charges are immobile, and are found inside the nuclei of atoms as Protons. Negative charges can be mobile, and have the source of electrons. These orbit the nuclei of atoms, and can be stripped from the atoms to be used as mobile charged through conductors, such as electricity moving through wires.
Charges of atoms are changed by the movement of?
Charges are changed by the movement of electrons to or from an atom.
Do atoms have a higher number of positive charges or negative?
Normally atoms are neutral.
When electrons were discovered scientist inferred that neutral atoms contain positive charges because?
Scientists inferred that nuetral atoms contained postitive charges, because electrons contained negative charges.
What part do the charges of the atoms parts play in the movement of electrons between atoms?
none
What atoms have no overall charge?
Atoms, by definition, have no charge. If they had charges, they would be called ions.
Do ionic bonds form between ionized atoms?
Yes, only if there are both ions with positive charges and ions with negative charges among the ionized atoms.
Atoms have higher number of positive charges than negative charges?
the positive number of a atom
