Why do atomic masses have decimal points and look scary?
Most elements exist in the form of isotopes: these are atoms all have the same number of electrons and protons but the number of neutrons varies from one isotope to another. As a result, each isotope of an element has a different atomic mass. The atomic mass given for an element is an average of these atomic masses, weighted together according to the isotope's abundance on earth. That is why they have decimal points and fractional parts.They d not look at all scary! After all, what can numbers do to you? You are much bigger than them!
What the number of neutrons in boron?
It depends on what isotope you are asking for, or if you are asking for an isotope at all.
What is the mass number lead?
Lead is a metal element. Atomic mass of it is 207.
How many neutrons do silicon have?
Silicon has 14 protons, so it typically has 14 neutrons as well to maintain a stable atomic structure.
Is an isotope a positively charged particle?
No. An element is a type of atom; distinguished by the number of protons; an isotope might be considered a "sub-type", distinguished by the number of neutrons. In other words, different isotopes of the same element have the same number of protons, but the number of neutrons varies. This is completely unrelated to the electric charge.
What is the atomic number and atomic mass number for aluminum?
The numbers of protons and electrons in any neutral atom are the same as the atomic number, 13 for aluminum. The number of neutrons varies by isotope and can be found by subtracting the atomic number from the atomic mass number. One isotope is Al-27, in which there are 14 neutrons.
What is the difference between atomic number and atomic mass number?
Atomic number is the number of protons in the nucleus of an atom, and each element has a unique atomic number that is the same for all of its atoms. Mass number is the number of protons and neutrons in the nucleus of a specific isotope of an element. Mass number varies with different isotopes because of different numbers of neutrons.
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.
How many protons electrons neutrons in carbon?
Carbon has 6 protons, 6 electrons, and 6 neutrons because 12.011 is rounded to 12.000 so 12.000-6=6 so 6 neutrons.
What is heavier one atom of indium or one atom of zirconium?
You can find this by looking up the atomic weights to get the "average" for an atom In is 114.82 Zr is 91.224 If the atomic weights are close you may have to check for isotopes if tou think the questioner is really asking about individual atoms where the atomic mass varies. The isotopes of Indium are 113In and 115In Zr has a number of stable isotopes ranging from 90Zr to 94Zr So the lightest Indium isotope 113In is heavier than the heaviest isotope of Zr, 94Zr.
What is the disintegration rate of radioactive elements?
It varies from one element to another. It is measured in terms of its half-life. A half-life is the length of time it takes for half the number of radioactive atoms of the element in a lump to decay.
How many neutrons does iron have?
It varies. Iron is element 26 with a relative atomic mass of 55.85That means that the naturally occurring isotopes must have a range of neutrons.92% of iron atoms have 30 neutrons, 8% have 28 neutrons; 2% have 31 neutrons and there is a small percentage
