How are the structures of the chlorine atoms and different?

The number of protons an atom has, also known as the atom’s atomic number, determines which element it is. All atoms which contain 17 protons are called chlorine atoms. Since all atoms of chlorine contain 17 protons, chlorine-35 and chlorine-37 differ in the number of neutrons each one has.

What changes an atom to make an isotope?

Isotopes are atoms that have the same number of protons and electrons, but a different number of neutrons. Changing the number of neutrons in an atom does not change the element. Atoms of elements with different numbers of neutrons are called “isotopes” of that element.

What is it in the atoms of one element that must be changed so that the element is changed to another element?

Nuclear transmutation is the conversion of one chemical element or isotope into another. In other words, atoms of one element can be changed into atoms of another element by transmutation.

How does an atom get changed into a different atom?

Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom’s atomic number. So, adding or removing protons from the nucleus changes what element that atom is!

What are the similarities and differences of isotopes?

Isotopes are atoms of the same element that contain an identical number of protons, but a different number of neutrons. Despite having different numbers of neutrons, isotopes of the same element have very similar physical properties.

Why do all elements have isotopes?

Elements have families as well, known as isotopes. Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table. Every element has its own number of isotopes.

Can an atom be changed from one element to another?

Nuclear transmutation is the conversion of one chemical element or an isotope into another chemical element. A transmutation can be achieved either by nuclear reactions (in which an outside particle reacts with a nucleus) or by radioactive decay, where no outside cause is needed.

Which is not represented Bohr’s model of an atom correctly?

16. Which of the following in Fig. 4.2 do not represent Bohr’s model of an atom correctly? The first shell can have a maximum of 2 electron and the second shell can have a maximum of 8 electrons hence ii and iv do not represent Bohr’s model of an atom correctly.

What happens to an atom when it gains an electron?

This happens when an atom gains or loses electrons. The number of protons never changes in an atom. More electrons means a negative charge and fewer means a positive charge. Once an atom has an electrical charge it is called an ion. In an ion the atomic number and atomic mass do not change from the original.

How does the number of protons in an atom change?

The number of protons never changes in an atom. More electrons means a negative charge and fewer means a positive charge. Once an atom has an electrical charge it is called an ion. In an ion the atomic number and atomic mass do not change from the original.

How does the number of neutrons affect the mass of an atom?

Therefore, the number of neutrons in an atom contributes significantly to its mass, but not to its charge. Electrons are much smaller in mass than protons, weighing only 9.11 × 10 -28 grams, or about 1/1800 of an atomic mass unit. Therefore, they do not contribute much to an element’s overall atomic mass.
