Which element does not have any neutron in this atom?
Hydrogen is the only element without any neutrons.
How many neutron are in oxygen?
There are 8 neutrons in oxygen. You can determine the number of neutrons in any element by subtracting the atomic number (which is 8 for oxygen) from the atomic mass, rounded to the nearest whole number (which is 16 for oxygen). This is because the mass of any element comes mainly from the protons and the neutrons - the mass of the electrons is too tiny to be a significant contribution. The atomic number corresponds to the number of protons in an element, so when you subtract it from the element's total mass, you are left with the number of neutrons.
Determine the number of protons?
The number of protons is equal to atomic number and the number of electrons (for a neutral atom).
How do you find the number of neutrons when an element has a charge?
Neutrons are neutrally charged. It is not possible to determine the charge of an atom through knowledge of the number of neutrons contained within its nucleus. Consider hydrogen, for example. It has no neutrons, one proton, and one electron. Its charge is neutral. Deuterium is hydrogen with a neutron, but also has the same charge. Tritium is hydrogen with two neutrons within its nucleus--again, no charge.
What is make an atom isotope?
It is the neutron that makes changes in atomic nuclei to change them from one isotope to another. For any given element, that element will have a fixed number of protons. It is, after all, the number of protons that determine the elemental identity. But the number of neutrons in a given element can vary, and we use the term isotope to talk about which particular atom we're investigating. That is, we apply the term isotope to speak to an atom of a given element with a certain number of neutrons in its nucleus.
Which of the following is unique for any given element A the number of protons B the number of neutrons C the charge on the electrons D the mass of the neutron?
its atomic numberthe number of neutrons
What is the rule of a set of numbers?
The only rule for any set is that given any element [number], you should be able to determine whether or not it is a member of the set.
Avogadro did experiments to determine avogadro's number?
No! Avogadro just guessed the average number of molecules,ions,atoms number in one mole of any compound,element,etc.
Use electronegativity values to determine the one element that has always has a negative oxidation number when it appears in any binary compound?
Flourine
How many electrons and protons are in an element with an atomic?
put it in your mind! The Atomic number. is number of protons, While The Mass number. is number of protons and electrons. when you subtract both get the number of electrons and this for any element but not all elements have same atomic numbers or mass and Rutherford First discover "transmutation" from element to other element which determine by their atomic and mass numbers.
What element has 1 neutron and 2 electrons?
The mass number is the sum of the number of neutrons and protons. If we already know that there is one neutron and the mass number is two, then that means there is one proton. Any atom with one proton is hydrogen. This particular isotope is called deuterium.
Which two subatomic particles are present in equal number in every atom of the same?
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.
