Why must the number of protons always stay the same in an atom?
The number of protons in an atom determines its identity as a specific element. Changing the number of protons would result in a different element. Therefore, the number of protons must remain constant in order to maintain the stability and characteristics of the atom.
An atom of any element must contain?
An atom of any element must contain protons, neutrons, and electrons. The number of protons in the nucleus determines the element's identity, while the neutrons and electrons help determine its stability and reactivity.
The atomic number of an element indicates the number of .. in an atom?
The atomic number indicates the number of protons in an atom of a particular element. The atomic number must be an integer (counting number), and is unique to that specific element.
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.
What particle in a nitrogen atom must remain the same in order for it to stay a nitrogen atom?
The atomic number for nitrogen is 7, meaning that it has 7 protons. In order for it to remain as nitrogen, the number of protons in it must always be 7. If, for example, the number of protons were to increase to 8, it would no longer be nitrogen; it would then be oxygen.
If an atom has 16 protons that atom must be which element?
Sulfur, which atomic number (in the PS) is 16, by definition equal to the number of protons in the nucleus
Why must the number of protons always stay the same in an atom?

What part of an atom must change for the atom to become a new element?
An atom must gain or lose protons from its nucleus to become an atom of another element. The number of protons, and to a much lesser extent the number of neutrons, will determine the chemical properties of an element.
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.
An atom of any element must contain?
An atom of any element must contain protons, neutrons, and electrons. The number of protons in the nucleus determines the element's identity, while the neutrons and electrons help determine its stability and reactivity.
The atomic number of an element indicates the number of .. in an atom?
The atomic number indicates the number of protons in an atom of a particular element. The atomic number must be an integer (counting number), and is unique to that specific element.
Why must there be a balance of protons to electrons in a element?
They have opposite charges, and an atom should be neutral.
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.
What particle in a nitrogen atom must remain the same in order for it to stay a nitrogen atom?
The atomic number for nitrogen is 7, meaning that it has 7 protons. In order for it to remain as nitrogen, the number of protons in it must always be 7. If, for example, the number of protons were to increase to 8, it would no longer be nitrogen; it would then be oxygen.
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.
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.
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.
