Whats a type of number that equals the amount of protons inside a nucleus and electrons outside a nucleus?
Atomic Number
How are electrons protons and neutrons positioned within an atom?
Electrons are on the outside rings of an atom. neutrons and protons are together in the nucleus of the atom. There is always the same number of protons and electrons in an atom, equal to the atomic number of the element. The amount of neutrons varies, even between atoms of the same number, these varieties of an element are called isotopes. If the amount of protons and electrons varies, it is called an ion, and the chemical number is still equal to the amount of protons.
What an atom is made of?
The correct grammar is 'What is an atom made of?', and the answer is that the nucleus is surrounded by Neutrons (no charge) and Protons (positive charge), and outside the nucleus are outer rings with Electrons (negative charge) on them. The amount of subparticles depends on the atom.
How is mass number related to the nucleus?
The mass number is the amount of neutrons within the nucleus minus the amount of protons/electrons.
The atomic number of an element is what?
The atomic number of an element is how many protons and electrons (you must have the same amount of protons as electrons) an element has in it's nucleus. The Atomic number= number of protons= number of electrons.
Protons neutrons and electrons combine to form what?
Protons, neutrons, and electrons can form any type of atom on the Periodic Table of Elements.The amount of protons determine what type of element an atom is.If the number of neutrons differ from the stable amount it should have, the atom is known as an isotope.If the amount of electrons differ from the amount of protons, the atom is known as an ion.
What subatomic particles are responsible for the mass of oxygen?
Mass of oxygen or any atom is mostly tied up in the nucleus and largely attributed to neutrons and protons. A smaller amount of mass is contributed by electrons in orbitals outside the nucleus.
How many electrons protons nucleus does a lemon have?
The same as the amount of apples in an orange. Sorry.
A neutral atom always has what?
Atoms are mostly empty space. They do have a nucleus. This contains subatomic particles. Protons. neutrons, and electrons are all subatomic particles. Protons carry a positive charge. Neutrons carry a neutral charge Electrons carry a negative charge. You may want to see the Bhor/plum-pudding model for more information.
Gold has an atomic number of 79. What does the 79 mean?
The number 79 means that there are 79 protons in the nucleus of an atom of gold. It is the number of protons/electrons in that atom (I say protons/electrons because there are an equal amount of both; i.e. 79 protons 79 electrons)
Difference between Na and Na plus?
Na+ will be a sodium atom that has lost an electron. Normally in atoms the amount of protons and electrons are equal, when you see a plus or minus charge on an atom its due to the loss or gain of electrons.
How do you calculate number of electrons required for the reaction?
For each element, the number of protons it has is equal to the number of electrons it has. However, if the atom has a different amount of electrons, then the charge will tell you that. If the charge is negative (-) then that says how many electrons the atom has gained, and if the charge is positive (+) then that says how many electrons the atom has lost.
