The atomic number of an element is what?
The atomic number of an element is how many protons and electrons (you must have the same amount of protons as electrons) an element has in it's nucleus. The Atomic number= number of protons= number of electrons.
If an element has 12 protons and 17 neutrons how many electrons must it have?
The number of electrons in a neutral atom is equal to the number of protons, so in this case, the element must have 12 electrons.
How many protons and electrons must an element have to be neutral?
zero
If the atomic number of an element is five how many protons does the element have?
Neutrons do not affect the neutrality (or charge) of an atom; protons and electrons do. In order to be neutral, the number of protons must be the same as the number of electrons.
A stable atom has equal numbers of?
Having an equal number of anything does not make an atom stable.
Neutral atom of a certain element has 15 electrons?
What is element 15? If it's the element on the periodic table with the atomic number 15, it would be Phosphorus which does have electrons, 15 of them. All elements on the periodic table have electrons.
What element has 2 electrons and 7 protons?
The element with 2 electrons and 7 protons is nitrogen. It has an atomic number of 7, which corresponds to the number of protons in its nucleus. The number of electrons in a neutral atom is equal to the number of protons.
In an atom the number of electrons must be the same as the number of?
protons, because the protons are positive and the electrons are negative so to have a neutral atom the protons and electrons must be balanced
The number of electrons and protons in a neutral atoms must always what?
#of electrons and # of protons is EQUAL in a neutral atom
If an element has 12 protons and 13 neutrons how many electrons dose it have?
12 electrons. Remember, electrons and protons must be balanced in charge; neutron number may vary.
How is it possible for an element to have more electrons than protons?
No. In a normal, neutral atom of an element the electrical charges MUST balance out which means that there must be equal numbers of Protons and Electrons. If, in a chemical reaction, an atom gives up or gains and electron, it then ceases to be an atom and becomes an "ion" and is only stable while it is partnered with the other "ion" sharing the electron(s).
How many electrons are lost or gained if there are 4 electrons 4 protons?
If there are 4 electrons and 4 protons, the atom is electrically neutral since the positive charges from the protons balance out the negative charges from the electrons. No electrons are lost or gained in this scenario.
