What else can I help you with?
What particles have negative electric charges equal to the positive charges of the protons?
The electrons; their negativity cancels out the protons' positivity so the atom is electrically neutral.
What do all atoms have the same number of?
Atoms contain equal numbers of protons and electrons until they are ionized into a charged species or "ion."
If an atom contains 15 electrons it will also have 15?
Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
Does the number of protons always equal the number of electrons?
In the atom state (not ionic), yes.
Can the number of protons always equal the number of electrons in an atom?
This is not a general valid rule; ions have a different number of electrons.
Are protons and electrons equal in magnitude?
No, A proton is 1836 times heavier than that of electron.So they are not equql in magnitude
In an atom the number of protons is always equal to the number of what?
No - in fact it is quite rare
What subatomic particle is always equal in neutral atoms?
protons and electrons will always be = number
In an atom the number of protons is always equal to the number of?
In a neutral atom, the number of protons is always equal to the number of electrons.
What particles have negative electric charges equal to the positive charges of the protons?
The electrons; their negativity cancels out the protons' positivity so the atom is electrically neutral.
The number of electrons and protons in a neutral atoms must always what?
#of electrons and # of protons is EQUAL in a neutral atom
Does the number of protons always equal the number of electrons in a atom?
No
Are protons and electrons always equal?
yes,,,because the number of protons is equal to the number of electrons. No, when electons are lost or gained by an atom (number of protons stays the same) the atoms become 'ions,' which are positively or negatively charged respectively.
What two things are always equal within an atom?
The number of protons in the atom's nucleus and the total number of electrons in the electron shells of that atom.
Is the number of valence electrons equal to the number of protons?
No, the number of valence electrons is not always equal to the number of protons. The number of valence electrons is determined by the group number of an element on the periodic table, while the number of protons is the atomic number of the element.
What two particles in an atom always have the same number?
Protons and electrons in an atom always have the same number, which determines the atom's overall charge. The number of protons is equal to the atomic number of the element, while the number of electrons is equal to the number of protons in a neutral atom.
Why does the atom have no overall charge?
The atom has no overall charge because it contains equal numbers of positively charged protons and negatively charged electrons. The positive charge from the protons balances out the negative charge from the electrons, resulting in an atom that is electrically neutral.
