What else can I help you with?
How many numbers of protons are in fluorine?
Fluorine has 9 protons.
What do different elements have different numbers of?
Different elements have different numbers of protons. The number of protons identifies the element.
Atom does not have to have equal numbers of protons and?
neutrons in order to be stable. The number of protons determines the element's identity, while the stability of the nucleus is influenced by the balance of protons and neutrons. Isotopes can have different numbers of neutrons while maintaining the same number of protons.
Why are all atomic numbers whole numbers?
The atomic number is the number of protons.
How do the number of protons compare to the number of electrons in an atom with a neutral charge?
The numbers of protons and the numbers of electrons balance; they are equal.
How many numbers of protons are in helium?
2 protons as its atomic number is 2
Are found in the same numbers as protons?
The number of protons is equal to the atomic number.
How are isotopes identifield?
By the numbers of protons
Why are there not isotopes with unusual numbers of protons?
If the number of protons changes so does the element, as the number of protons defines the element.
What is the name given to atoms of the same element that have the same number of protons?
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
Does a noble gas have twice as many electrons as protons?
equal numbers of protons and electrons
Do an atom have an equal numbers of protons and electrons?
no
