Where is most of the mass of an atom contained?
When calculating the mass of an atom, you add the mass of the protons and the neutrons. This is the nucleus of the atom. The electrons are small enough to be ignored except in the most delicate calculations.
How to calculate the mass of an atom?
To calculate the mass of an atom, you can add up the masses of its protons, neutrons, and electrons. Protons and neutrons have a mass of about 1 atomic mass unit each, while electrons have a much smaller mass that can usually be ignored. The total mass of an atom is usually given in atomic mass units (amu).
How many protons would be in a atom with a atomic number of 19 and a mass of 40?
Mass is irrelevant when determining the number of PROTONS. The atomic number is the number of PROTONS so the answer is 19. Mass is approximately number of PROTONS plus the number of NEUTRONS. ELECTRONS mass is so small compared to protons and neutrons that they are usually ignored.
How do you figure out how many neutrons are in a a atom?
Each nucleon (proton or neutron) contributes about 1 atomic mass unit to the mass of the atom. The mass contribution of the electrons can be ignored, since it takes about 1800 of them to equal the mass of a nucleon and the heaviest elements known have around 1/15th that number of electrons. So if you subtract the atomic number (number of protons) from the atomic mass rounded to the nearest whole number (number of nucleons), what's left is the number of neutrons.
What is the number of neutrons in boron?
There are 6 neutrons.
Can neutrons cause static electricity?
No. The movement of electrons is what causes electricity, and neutrons take no part in it.
When figuring atomic mass the mass of is ignored?
When calculating atomic mass, the mass of electrons is typically ignored because it is so small compared to the mass of protons and neutrons. Electrons have a much smaller mass relative to protons and neutrons, so they do not significantly contribute to the total atomic mass of an atom.
How does electricity travel through fruit?
If enough protons and neutrons are in the fruit it can produce electricity
What words can describe electricity?
There are many key words to understand when discussing electricity. Electricity flows in a current. The unit of power of electricity is a watt which refers to the rate of work done. A volt is force at which electricity moves from its origin through a conductor and to the place of use.
Is static electricity is an excess of neutrons?
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy.
What lightning made out of?
lightning id a large discharge of electricity. it contains nothing but electrons and neutrons.
Is it recloser or reclosure when talking electricity?
The correct term is "recloser" when discussing electricity. Reclosers are devices used to automatically restore power after a temporary fault on an overhead power line.
Two electronics students are discussing static electricity Student A says that a basic property of static electricity is the fact that it can't be detected Student B says that an electric current re?
student b
Why do you say the mass of any element is in the nucleus and you ignore the mass of the electrons?
The mass of any atom is in the nucleus because it contains both protons and neutrons. Protons and neutrons have a significantly greater mass than electrons do, so electrons are ignored when finding the mass of an atom.
Where is most of the mass of an atom contained?
When calculating the mass of an atom, you add the mass of the protons and the neutrons. This is the nucleus of the atom. The electrons are small enough to be ignored except in the most delicate calculations.
Is static electricity an excess of neutrons?
Static electricity is not an excess of atoms, but rather differences in the charges of those atoms. Static electricity happens when there is a separation of positive and negative charges caused by electrons moving from one material to another.
Why do electric eels produce electricity if electricity and water dont mix?
They release neutrons and protrons and when in contact with a human in the water it creeats an electrict energy field or force received by the flesh
