Does 12C have fewer neutron than 13C?
Yes. Both carbon atoms have 6 protons. However, the 12C atom has 6 neutrons while the 13C atom has 7 neutrons :)
The total number of protons amd neutrons in the nucleus determines the atoms?
This is the "mass number" of the atom, indicating relative mass of an isotope.For example uranium-235 (235U) is a lighter atom than uranium-238 (238U) because while both isotopes have 92 protons (the atomic number), the first has 3 fewer neutrons.
Does thyroxine have fewer iodine atoms than triiodothyronine?
No. Thyroxine is also called as tetraiodothyronine. So thyroxine has four iodine atoms and triiodothyronine has three iodine atoms.
Does polyunsaturated fats has fewer hydrogen atoms than saturated fats?
Yes, polyunsaturated fats have fewer hydrogen atoms than saturated fats because they contain double bonds in their carbon chains, which leads to a reduction in the number of hydrogen atoms that can bind to the carbon atoms.
Why isotopes of an element with fewer neutrons have lower densities and lower melting and boiling points?
Isotopes with fewer neutrons have less mass, leading to weaker intermolecular forces, resulting in lower densities and lower melting and boiling points compared to isotopes with more neutrons. The presence of more neutrons increases the mass and the strength of intermolecular interactions, thus increasing the density and melting and boiling points.
Will an atom with more neutrons react identically to an atom of the same element with fewer neutrons?
Not always. Some atoms of the same element with different numbers of neutrons are radioactive, whereas the other atoms are not.
Does 12C have fewer neutron than 13C?
Yes. Both carbon atoms have 6 protons. However, the 12C atom has 6 neutrons while the 13C atom has 7 neutrons :)
What is an atom with more or fewer neutrons than atoms of the same element?
An atom of a certain element with a different number of neutrons compared with the common form of the element is called an isotope. Isotopes have the same number of protons and electrons in an atom, but a different number of neutrons (which means that they have a different atomic mass number).
Some atoms may have more or fewer what than will other atoms of the same element?
Neutrons in the nucleus, so you have isotopes of the same element, For example hydrogen, deuterium and tritium.
Do all atoms contain proton neutron and electron?
yes, all normal atoms do, but there are things called ions and isotopes that have fewer or more electrons and neutrons
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
What gaseous element has 5 valence electrons and fewer neutrons than sodium?
The gaseous element with 5 valence electrons and fewer neutrons than sodium is Boron. Boron has 5 protons and 5 neutrons, while sodium has 11 protons and about 12 neutrons.
Does U-235 have fewer neutrons than common uranium?
Uranium-235 has 143 neutrons; uranium-238 has 146 neutrons. Each isotope has a different number of neutrons.

What element has fewer or more neutrons than protons?
The vast majority
If the isotope is given for calcium what is the formula?
An isotope has extra/fewer neutrons than the original atom. So if you know the isotope you can deduce the original atoms' formula.For Ca that would be:20 protons40 mass number
Does a sodium atom have fewer neutrons in its nucleus than an iron atom?
Yes. Sodium has 12 neutrons whereas iron has 30 neutrons for their most stable isotpe.
