How much do isotopes that share an element differ in the number?
Isotopes have a different number of neutrons but the number of protons and electrons is the same.
What Is the weighted average of all of the isotopes of an element.?
The answer is the atomic weight of the original element: It's the number on the top left of each element square of the Periodic Table.
How is isotopes related to number of electrons?
An isotope is not really related to the number of electrons, but rather it is determined by the number of neutrons.
Different isotopes of an atom retain the properties of the atom-?
Isotopes of an atom does retain the properties of the atom. This is discrete in units of matter.
What element was made by bombarding plutonium and alpha particles?
The reaction is:
Pu-239 + alpha = Cm-242 + n
How is an isotope of hydrogen with atomic number 2 and mass number 4 written?
This case is impossible. Hydrogen will always have an atomic number of 1.
How are Xe-129 and Xe-130 same and how are they different?
They have the same number of protons (54) and electrons. 130Xe has one more neutron in the nucleus.
What is the nuclear composition of the common isotopes of N?
The natural isotopes of nitrogen are: 14N with 99,634 % and 15N with 0,366 %.
What are the safety issues of carbon-14?
Carbon-14 poses minimal safety issues due to its low radioactivity and short half-life of 5,730 years. Exposure risk is typically only a concern for individuals working directly with concentrated sources of carbon-14, where precautions such as shielding and proper handling are necessary. In general, carbon-14 is not considered a significant health hazard in most everyday situations.
Which is a correct representation of the isotope of sodium with 13 neutrons?
Isotope 24Na (or Na-24) has 11 protons and 13 neutrons, its mass number is 24
Isotope 23Na is the stable form of Na with 11 protons, 12 neutrons and with mass number 23.
Nitrogen-14 and nitrogen-15 are isotopes of the same element. How do these isotopes?
Nitrogen-14 has 7 protons, 7 electrons, and 7 neutrons. Nitrogen-15 has 7 protons, 7 electrons and 8 neutrons. So, the only way they differ is in the NUMBER OF NEUTRONS.
What is the least abundant isotope of hydrogen?
These are the Hydrogen isotopes with the least mass:
Hydrogen 1-protium
Hydrogen 2-deuterium
Hydrogen 3-tritium
