There are no stable isotopes with Atomic Mass 8. A boron ion could reasonably have charge +3, but 8B is very radioactive with a half life of less than a second.
What else can I help you with?
Does atomic mass has a positive change?
No. Atomic mass is a measure of mass, not charge.
What and what make up the atomic mass?
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. Protons have a positive charge and neutrons have no charge, contributing to the overall mass of the atom. The number of electrons, which have a negligible mass, is not included in the atomic mass.
What 2 factors determine the atomic mass of a number?
The atomic mass of an element is primarily determined by the number of protons and neutrons in the nucleus of its atoms, collectively known as nucleons. Protons contribute a positive charge and a mass of approximately 1 atomic mass unit (amu), while neutrons contribute a similar mass but no charge. The atomic mass unit is a weighted average of all the isotopes of an element, reflecting both their mass and natural abundance. Electrons have negligible mass and do not significantly affect the atomic mass.
Which particale has a mass of approximately one atomic mass unit and a unit positive charge?
The particle with one unit of positive charge is Proton. Answer Proton
Which one particle has a mass of approximately atomic mass unit and a unit positive charge?
none of the particles are 1g. (g stands for gram which is about the weight of a small paperclip.) however the proton has a positive charge.
Does the atomic mass tell how many atoms are in an element?
The atomic mass tells how much amu one atom of an element weighs. It, minus the atomic number, rounded to the nearest one, gives you the number of neutrons in an atom. The atomic number is the number of electrons and protons. Protons have a positive charge, electrons have a negative charge, and neutrons are neutral.
What is the charge to mass or atomic no to atomic mass ratio for a element to call it aradio active element?
An An element is considered radioactive if it is so large and unstable that it releases electromagnetic waves and/or neutrons and deteriorates into elements with smaller atomic numbers.
What is the concentration of positive charge and mass in Rutherford's atomic model called?
nucleus
What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
What element has 1 amu with no charge?
The element hydrogen has a mass of approximately 1 atomic mass unit (amu) and is typically shown as having no charge in its most common form.
What determine an atoms size?
The atomic radius depends on the the number of electron shells, total negative charge, positive charge of the nucleus, atomic mass.
Which of the following determines the identity of an element atomic number mass number atomic mass or overall change?
Atomic number determines the identity of an element. It represents the number of protons in an atom's nucleus, which is unique to each element. Mass number refers to the total number of protons and neutrons in an atom's nucleus, while atomic mass is the average mass of an element's isotopes. Overall charge is determined by the number of protons and electrons in an atom, but it does not uniquely identify the element.
