If you mean protons and electrons then protons are positive and electrons are negative, so the protons and electrons cancel each other out leaving the atom stable. If the numbers were uneven, the atom would be unstable and decay, but that doesn't mean that all unstable atoms have an uneven number of protons and electrons.
What else can I help you with?
The number of these must be the same for all atoms of an element?
The number of protons is identical in all atoms of an element.
What must atoms of the same element have?
All atoms of the same element have the same number of protons, which is its atomic number. A neutral atom will have the same number of electrons as protons.
What atoms of the same element contain the same number?
Atoms of the same element must contain the same number of protons. This is because of the positive charge they provide.
Can the neutral atoms of tow different element have the same number of electron explain?
NO. The number of electrons in any neutral atom must be the same as the number of protons. The number of protons is the atomic number, if the atomic number is the same then the atoms are of the same element, not different ones.
How many protons are in an atom of a pure element?
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
Why can 2 atoms of the same element have different numbers of neutrons but must always have the same number of protons?
They are called Isotopes
Why atomic number of an element indicates as the number of protons in the atom?
The atomic number of an element represents the number of protons in the nucleus of an atom. Since atoms are electrically neutral, the number of protons in the nucleus must be equal to the number of electrons outside the nucleus, making the atom overall neutral.
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.
Why can 2 atoms of the same element have different numbers of neutrons but must always have the same number of protons explain please?
Atoms of the same element have the same number of protons because the number of protons defines the identity of the element. However, isotopes of an element can have different numbers of neutrons which doesn't change the element's identity but can affect its atomic mass. This variation in neutron number creates isotopes with different mass numbers but the same atomic number.
How do you determine the number of protons in the nucleus?
The number of protons in an atom determines the chemical identity of that atom. (And only that, by the way.) We use the atomic number to state the exact number of protons in all atoms of a given element. Hydrogen has the atomic number 1 because every atom of hydrogen has exactly one proton. Also, every atom with exactly one proton is hydrogen. Helium is atomic number 2, and the same thing applies. All helium atoms have exactly 2 protons, and all atoms with exactly 2 protons are helium atoms. To determine the number of protons in a given atom, look at which element it is and find it on the periodic table or on a list of the elements. Then find its atomic number, which will be the exact number of protons in every atom of that element.
Does an element's number of valence electrons equals the element's number of protons?
Only hydrogen and helium have the stated property. For all heavier elements than these two, the number of valence electrons is less than the total number of electrons, which must be the same as the number of protons in all neutral atoms.
How many protons does hydrogen-1 have?
HydrogenAll atoms, ions, and isotopes of the same element have the same number of protons. The number of protons defines the element. Hydrogen atoms all have one proton. So it does not matter if you provide the mass number (hydrogen-1) because the number of protons does not depend on it. It does, however, let us know the number of neutrons. The mass number is the sum of the number of protons and neutrons. Because we know that hydrogen has one proton, and the mass number is one, there must be no neutrons.
