Under normal conditions, i.e. non-ionic, the number of protons is equal to the number of electrons.
There're two particles in the atom nucleus (protons and neutrons)
The two subatomic particles you add together to get the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but together they contribute to the mass of an atom.
The two sub-atomic particles located in the nucleus of an atom are protons and neutrons. Protons carry a positive charge, while neutrons have no charge.
The number of protons in an atom determines the identity of the element.See these two related questions for more information:[http://wiki.answers.com/Q/What_is_the_atomic_number_and_what_does_it_tell_you_about_the_number_of_protons_in_an_atomWhat is the atomic number and what does it tell you about the number of protons in an atom?]and[http://wiki.answers.com/Q/How_do_you_find_the_number_of_protons_and_electrons_and_neutrons_in_an_atomHow do you find the number of protons and electrons and neutrons in an atom?]
The particles of water are called molecules, composed of two hydrogen atoms and one oxygen atom.
Electrons and protons.
protons and electrons.
Protons and electrons in an atom always have the same number, which determines the atom's overall charge. The number of protons is equal to the atomic number of the element, while the number of electrons is equal to the number of protons in a neutral atom.
The number of protons and electrons in an atom are equal in numbers. Protons have a positive charge and are found in the nucleus, while electrons have a negative charge and orbit the nucleus.
In each neutral atom of any given element, the numbers of electrons and protons are equal, as the charges in the atom must balance. Only the neutron number may vary amongst atoms of the same element.
Protons and electrons.
No. of electrons and no. of protons are equal to atomic no. Since, protons are positively charged and electrons are negatively charged They cancel each other's charge and hence, the atom is neutral as a whole.
There are two types of particles in the nucleus of an atom, which are the Protons and the Neutrons. The number of particles in the nucleus depends what is the element. For example, Oxygen has 8 protons and 8 neutrons in the nucleus and Phosphorus has 15 protons and 16 neutrons in the nucleus.
Alpha particles are emitted from the atom taking with it 2 protons and (I am pretty sure) two neutrons. This will change the atomic number of the atom and the atomic weight.
Only for hydrogen and helium are these two numbers the same. All other elements have at least two non-valence electrons, and the total number of electrons must be equal to the number of protons. Therefore, in all elements except hydrogen and helium, the number of valence electrons is less than the number of protons.
Under normal conditions, i.e. non-ionic, the number of protons is equal to the number of electrons.
