The negative charges of their electrons repel each other.
Electrons carry negative charges and just like when you hold two negative sides of a magnet together they push away from eachother. (if they had opposite charges they would attract)
The negative charges of their electrons repel each other.
APEX!!!
Forces between electron pairs push the atoms apart.
the number of valence electrons in the atom's outer shell how much the valence electrons are shielded from the nucleus
They don't. Electrons come and electrons go, and the nucleus doesn't much care.Radioactivity is the process of the nucleusfalling apart.
Carbon IS an atom. I presume you mean how many electrons there are. There are 6 electrons, 6 protons and 6 neutrons in every un-bonded Carbon atom.
In a neutral atom, as many as the atom's atomic number (or number of protons): 1 for hydrogen, 2 for helium, 3 for lithium, etc. However, the atom can also gain or lose electrons - converting it into an ion, and resulting in more or less electrons than the atomic number.
Much of the nature of an atom is determined by the configuration of its electrons. The configuration controls how freely it can bond, how charged the atom is, how stable it is, and other atomic properties.
Phosphorus has 15 electrons in the neutral atom.
These numbers actually vary between atom to atom.
In a normal atom there are 1 electron, but some are different.
In an atom, there are the same amount of protons as electrons, if that's what you mean.
If an atom has more protons then electrons the atom will have a negative charge.If the atom has more electrons then protons the atom will have a positive charge.If the atom has equal numbers of electrons and protons then the atom becomes neutral.However if you're wondering why an atom is stable then that means that it has all the electrons inside of it paired. If the atom is unstable it has unpaired electrons.
eight I believe
the number of valence electrons in the atom's outer shell how much the valence electrons are shielded from the nucleus
There are the same number of protons as electrons in each atom unless the atom does not have a neutral charge, if it has a negative charge it has that more electrons, and if it has a positive charge it has that much more protons hope this helps
No, since electrons are part of an atom, they are smaller -- much smaller. In fact, they weigh practically nothing.
When the number of electrons and neutrons are the same, it means that the number of protons will also be the same amount. For example a nitrogen atom has 7 electrons and 7 neutrons, this means that the number of protons will also be 7.
Yes, essentially one atom in the bond pulls on the electrons so much harder than the other, that they do share them to form the bond, but the more electronegative atom pretty much owns those electrons.
