Isotopes of an element have same number of protons and different number of neutrons. Hence similar in chemical properties and different in physical properties.

Is this true that a normal atom of oxygen has a mass of 16 the isotope oxygen 18 and protons 18?
true
Why is the einsteinium atomic mass a whole number?
For elements with no stable isotopes, the mass number of the isotope with the longest half-life is used.
Is it true that the periodic table is arranged by the number of neutrons?
No. For the most part, it is arranged by the number of protons. But even here there are exceptions.
What is the atomic structure for americium 241?
Americium has (all the isotopes) 95 electrons.
What statement is true about atoms protons neutrons and electrons?
Several come to mind. They are both found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. They are nearly the same size, though neutrons are a bit larger. The sum of the protons and neutrons in an isotope of an element is its mass number.
WHAT Equals the sum of the number of neutrons and protons in an isotope?
The atomic mass equals neutrons and protons. This is true in non isotopes as well.
Is this true that a normal atom of oxygen has a mass of 16 the isotope oxygen 18 and protons 18?
true
What is true about what's in the nucleus of every atom of He no matter what Isotope?
There are always two protons.
Why is the einsteinium atomic mass a whole number?
For elements with no stable isotopes, the mass number of the isotope with the longest half-life is used.
Why does boron-11 have 5 protons and 5 neutrons?
Boron-11 is an isotope. The atomic number of Boron is 5 which means it has 5 protons, (if there were more or less protons the element wouldn't be boron). the isotope number (11) is the number of protons plus neutrons. to find out the number of neutrons you would take take the isotope and subtract it by number of protons (11-5) which yields 6. To find the isotope add the number of protons to the number of neutrons.
How are atoms different from one another?
They are different because of the number of electrons in there electron cloud. True, the number of electrons are specific to the type of atom but so are the number of protons. The atomic number of the atom is directly related to the number of protons and electrons it has. So carbon for example is given the atomic number 6. Thus it has 6 protons and 6 electrons. It's atomic mass is 12.0107 amu. This we can round to 12. To aquire the atomic mass of a given element you add the number of protons and nuetrons together since the electrons are so infinitely small they are not considered to have any mass. We know from the atomic number that carbon has 6 protons, it's atomic mass is 12, so that means the number of nuetrons must also be 6. This doesn't exactly answer the question though. The obvious things that differentiate one atom from another are their atomic number, the number of protons and electrons inside an atom, and their atomic mass.
Is The identity of an element is determined by the number of protons?
Yes, it is true, the number of protons is equal to atmic number.
Is it true that the periodic table is arranged by the number of neutrons?
No. For the most part, it is arranged by the number of protons. But even here there are exceptions.
Is it true that the number of protons is different for the two isotopes?
Not; the number of protons in isotopes is identical; only the number of neutrons is different.
Is it true that the mass number is the number of protons and neutrons?
Yes, this is the definition of mass number.
How many protons does silicon have?
Silicon is the element 14 and has 14 protons and that whatever element the element is on the periodic table that's how many protons there will be in the element.Silicon is the element 14 and has 14 protons
Is N-14 or N-15 more abundant in nitrogen?
Nitrogen 14 is by far the most abundant isotope (99.63% abundant).An easy way to figure out which one is the most abundant is to look at the periodic table. The mass on the periodic table is the weighted average of all possible isotopes. The atomic mass of nitrogen is 14.00674. You can gather from this that the most abundant isotope is N-14, since the number is VERY close to 14.It is also possible to guess the most common isotope if you do not have access to a periodic table. Nitrogen has 7 protons and the most stable isotope is Nitrogen 14, which has 7 neutrons in addition to the protons. In virtually all elements, the stable isotopes are those that have the same or very similar number of neutrons as the number of protons in the nucleus. This works for Carbon which has 6 protons and 6 neutrons in the nucleus for Carbon 12, the most common isotope.This is also true for Oxygen 16 (8P and 8N), Silicon 28 (14P and 14N), and just about any element you choose.An isotope of nitrogen containing seven neutrons would be nitrogen - 15.
