The atomic number of C13 is still 6, the same as C12. The difference lies in the number of neutrons, not protons. The number of neutrons does not radically change the element, which is why they are called isotopes. The C13 isotope is 1.1% of all naturally occurring carbon atoms, the C12 group having 98.9%

How are neutrons in an atom calculated?
As an example, take Americium 241 - 241 is the atomic weight. It is Atomic number 95 in the periodic table and so there are 95 protons. There are thus 241 -95 = 146 neutrons. That principle applies to all the elements.
The atomic mass is equal to the sum of?
The Atomic Mass number of an element is the sum of the protons and neutrons in the nucleus of an atom of that element.The relative atomic mass is the average atomic mass number of all the known isotopes of an element.
Why does a mass of an atom changes if it an isotope?
yes it does b/c the isotopes have different number of neutrons so therefore isotopes cause a change in mass.
Is An atom of oxygen (atomic number 8) with an atomic mass of 16 would have how many neutrons a. 7 c. 8 b. 9 d. 6?
An atom of oxygen with an atomic number of 8 has 8 protons. The atomic mass of 16 indicates the total number of protons and neutrons in the nucleus. To find the number of neutrons, subtract the number of protons from the atomic mass: 16 - 8 = 8. Therefore, the correct answer is c. 8.
What atom has the atomic number 6?
You could look it up by just typing it into google (Just in case you ever need to know..) Carbon: C Atomic number: 6 (number of protons in nucleus) Atomic mass: 12.011 a.m.e. Mass number: 12 (=number of protons + neutrons in nucleus) Nonmetal

How an atom of C-13 is different from an atom of C-12?
An atom of C-13 has 1 additional neutron compared to an atom of C-12, which is a carbon isotope with 6 protons and 6 neutrons. C-13 is a stable and naturally occurring isotope of carbon found in small amounts in nature. The difference in the number of neutrons affects the atomic mass of the isotopes, with C-13 having a slightly higher atomic mass than C-12.
The atomic mass is equal to the sum of?
The Atomic Mass number of an element is the sum of the protons and neutrons in the nucleus of an atom of that element.The relative atomic mass is the average atomic mass number of all the known isotopes of an element.
what is the mass of an atom with 5 protons and 7 neutrons?
To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.
Why does a mass of an atom changes if it an isotope?
yes it does b/c the isotopes have different number of neutrons so therefore isotopes cause a change in mass.
Element A has atom which is 3 times lighter than that of Carbon-12 Calculate its atomic mass?
Mass of C-12 atom = 12 amu mass of C-12 atom = am So atomic mass of A = 4 amu source ; www.examville.com
Is An atom of oxygen (atomic number 8) with an atomic mass of 16 would have how many neutrons a. 7 c. 8 b. 9 d. 6?
An atom of oxygen with an atomic number of 8 has 8 protons. The atomic mass of 16 indicates the total number of protons and neutrons in the nucleus. To find the number of neutrons, subtract the number of protons from the atomic mass: 16 - 8 = 8. Therefore, the correct answer is c. 8.
What is half the mass of a carbon 12 atom?
hi well c-12 has not actually been given a unit. we know that the 12 means that it is exactly 12 units (unknown to us) in c-12. generally things are compared in relation to the mass of a c-12 atom. Something might be 1.5 times bigger relative to c-12 giving us X with 18 units. To answer your question, the half of the mass of c12 is 6 units. like i said unit is unknown but it is only used as a relative to compare the mass of other atoms because taking the mass of any one atom is irrelevant.
How do you calculate the number of protons neutrons and electrons in C-14?
In a carbon-14 (C-14) atom, the number of protons is equal to the atomic number of carbon, which is 6. Since the atomic number represents the number of protons, a C-14 atom has 6 protons. Neutrons can be calculated by subtracting the number of protons (6) from the atomic mass (14), giving 8 neutrons. In a neutral atom, the number of electrons is equal to the number of protons, so a C-14 atom would have 6 electrons.
What is the atomic number for 12C6?
The atomic number for carbon (C) is 6, indicating the number of protons in the nucleus of a carbon atom. The "12" in "12C6" refers to the mass number, which is the total number of protons and neutrons in the nucleus of a carbon-12 atom.
How many protons are there in an atom the element lithium if it has an atomic number of 3?
Lithium has 3 protons. The atomic number and the number of protons will be the same.
Which has greatest number of neutrons carbon13 and carbon14 or nitrogen14?
C-13 has an atomic number of 6 and an atomic mass of 13, therefore it has 13-6 neutrons = 7. C-14 therefore has 8 neutrons. N-14 has an atomic mass of 14 and an atomic number of 7, so its number of neutrons is 7. 8>7, so Carbon 14 has the largest number of neutrons.
