Why do you think changing the number of neutrons does not create a new element?
Because an element is defined by it's atomic number. Which is defined by the number of protons found in atom. Adding a neutron creates an isotope of an element.
What determines the element that an atom belongs to?
Its atomic number. In other words the number of positive protons in the nucleus of each atom and the number of negative electrons surrounding the nucleus of each atom.
What is shown in each element?
An atomic number is shown in each element.
Isotopes are atoms of the same element that have different atomic masses?
Yes. An element is defined by its atomic number, the number, or the number of protons in its nucleus. When an atom has more or less neutrons it is still the same element, but a different isotope of that element.
If the number of atoms of each element in the products equals the number of atoms of each element in the reactants the equation is?
In this case, the equation is balanced.
What does an atomic number tells you?
The atomic number tells you the number of protons in the nucleus. As such, it defines the element, since each element has a definite and defined number of protons. In the element, it also tells you the number of electrons, since the element (not the ion) has a neutral charge and protons = electrons.
Is the atomic number of an atom equal to the number of neutrons?
Only be coincidence; the atomic number is defined as the number of protons in a nucleus of each atom of the element.
How is the term atomic number defined for a given atom or isotope?
Atomic Number is the number of protons that an atom has. The atomic number is different for each element.
Defined what an element is?
The atomic number, the number of protons
How many neutrons make an atom?
That varies depending on the element and the isotope. An element is defined by its number of protons. This is called the "atomic number" of an element.
Why do you think changing the number of neutrons does not create a new element?
Because an element is defined by it's atomic number. Which is defined by the number of protons found in atom. Adding a neutron creates an isotope of an element.
Can An element be defined by the number of protons in the nucleus?
no
What is the top number mean in each element?
The top number in each element means the number of protons and electrons in the atom of that element.
How is atomic number used to tell one element from another?
The atomic number of an element stands for the number of protons in the unique atom of the element. The atomic number also is the same as the number of electrons. The atoms in each element differ from atoms in other elements by virtue of the number of positively charged protons in the atomic nucleus and the corresponding number of negatively charged electrons. The number of protons (or electrons) is the atomic number of the element. The atomic number ranges from 1 for Hydrogen to 92 for Uranium and then beyond through the transuranic elements created in laboratory conditions.
What determines the element that an atom belongs to?
Its atomic number. In other words the number of positive protons in the nucleus of each atom and the number of negative electrons surrounding the nucleus of each atom.
What is the number of atoms of each element?
each element has one atom of the element's name
What does each atom have a unique number?
Each element has a unique number of protons. If another atom has the same number of protons as that element, it is the same element.
