What is the symbol of an ion that has 20 protons 20 neutrons and 18 electrons?
The atomic number always equals to the number of protons. which in this case, is 20
How many protons neutrons and electrons are there in a neutral atom of 30P phophorus-30?
There are similar number of electrons and protons. it has 15 electrons and protons.
How protons and electrons in neon?
In an atom, 10 protons and 10 electrons. (# of protons = atomic number) =)
How can you use the periodic table to find the number of protons in one atom of an element?
valence electrons is the same as the number as the last digit in the group :)
What is the symbol for 2 electrons and 2 protons?
Number protons equal to atomic number. So the element is Helium
When is an atom neutral When mass number equals number of protons equals number of electrons or when atomic number equals number of protons equals number of electrons?
An atom is neutral when the number of protons in the nucleus equals the number of electrons surrounding the nucleus. This means that the atom has no overall charge, as the positive charge of the protons is balanced by the negative charge of the electrons. The mass number, which is the sum of protons and neutrons, does not necessarily impact the neutrality of the atom.
In a neutral atom the number of electrons equals the number of what?
The number of electrons should equal the number of protons, otherwise you have an ion.
How many electrons are in the mass number of 111 and protons of 50?
There are 50 electrons. In a neutral atom, the number of electrons equals the number of protons.
Does valence electrons equals number of protons?
YES!!!!
What is the number of protons in a neutral atom equal to?
The number of protons equals the number of electrons in an uncharged atom.
How can you find number of electrons in an atom?
In a neutral atom, the number of electrons equals the number of protons. The number of protons is the atomic number of the element on the periodic table.
What equals to the number of protons plus the number of electrons?
2 * Z
What is equal to the number of protons and electrons?
The atomic number of an element is equal to the number of protons, which also equals the number of electrons in a neutral atom.
How many protons and electrons are contained in an atom of element ruthenium?
An atom of ruthenium contains 44 protons and 44 electrons. This is because the number of protons in an atom determines its identity, and for a neutral atom, the number of protons equals the number of electrons.
What is the number of electrons in a neutral atom equals?
In a neutral atom the number of electrons is equal to the number of protons. The opposite charge between protons and electrons is what allows for a neutral atom.
What number of particles in an atom usually equals the number of protons?
Unless it is an ion, the number of electrons will equal the number of protons.
In a neutral atom is the number of protons equal to the number of electrons?
Yes. If the number is unequal, it is an ion.Yes that is correct. The atomic number is equal to the number of electrons which equals the number of protons
