What else can I help you with?
The atomic number of isotopes is determined by the number of atoms. true or false?
False. Number of neutrons.
How can an atoms mass number be determined?
it is the sum of the protons and neutrons present in the nucleus of the atom.
What is an isotope and how is it determined?
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. They are determined based on their atomic mass, which is the sum of protons and neutrons in the nucleus. Isotopes of an element have similar chemical properties but may have different physical properties, such as radioactive decay rates.
Why is not possible to determine the type of atom by simply knowing how many neutrons it has?
because the neutrons have no charge
What is the element that has a mass of 55 and contains 30 neutrons in its atoms?
The element with a mass of 55 and 30 neutrons in its atoms is zinc (Zn). This can be determined by subtracting the number of neutrons from the atomic mass of the element.
How can two atoms of the same element have different numbers of neutrons why doesnt the different number of neutrons make it a different element?
Neutrons have no significant effects on an atom's properties other than its mass. Nearly all chemical and physical properties of an element are determined by the configuration and number of electrons it has, which is in turn determined by the number of protons in the nucleus. As a result two atoms of the same element but with different numbers of neutrons (called isotopes) will behave identically.
Why are some atoms are heavier than others?
some atoms are heavier than others as they have higher relative Atomic Mass, by which is equals to proton number + number of neutrons in an atom, according to the Periodic Table of the elements
How do you find the number of neutrons in an elements atoms?
number of neutrons = mass number - atomic number
Do atoms have neutrons in them?
Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.
Do uncombined atoms have the same number of neutrons as protons?
Uncombined atoms have the same number of neutrons as protons only if they are isotopes of the element, which means the atoms have the same number of protons but different numbers of neutrons. Otherwise, atoms with the same number of protons and neutrons would be considered as different elements.
How may atoms of the same element differ from one another?
Atoms of the same element can differ from one another in their atomic mass, which is determined by the number of neutrons in the nucleus. These variations are called isotopes. Isotopes of the same element have the same number of protons but different numbers of neutrons.
Do all of the atoms of the same element have the same number of neutrons?
Yes, all atoms of the same element have the same number of neutrons.
