- Neutrons = 2 - 1 = 1 - Tritium (T): - Atomic number (Z) = 1 - Mass number (A) = 3 - Neutrons = 3 - 1 = 2 4. Conclusion: - From the calculations, we see that only Hydrogen (H) has 0 neutrons. Therefore, the atom that does not have any neutrons is Hydrogen. Final...

b. the number of neutrons in the nucleus of the atom. c. the number of electrons in the outer or Which of the following are formed elements: white blood cells, red blood cells, and/or platelets? From this neutral state, if the...
An atom is a neutral species that have the same number of protons and neutrons. When electrons are added or removed from an atom of an element, a charged species is formed known as ions. Answer and Explanation:1 Metals can lose electrons ...
A certain element has its outermost electron in a 3s subshell. It has valence +1 because it has 1 more electron than a certain noble gas. What element is it? a) Ar b) Ne c) Na d) Co e) He Find the probability that the electron in the ground state ...
The oxidation number is also known as the oxidation state. It states the number of electrons an element shares in an atom. It is also defined as the charge of an ion. The oxidation number is used in REDOX reactions. In those reactions, we determine the oxidation state of each atom to ...
Isotopes are variants of a particular chemical element that have the same number of protons (atomic number) but different numbers of neutrons. This results in different mass numbers for the isotopes of the same element. 2. Fundamental Particle of Difference: The fundamental particle that differs ...
Solution: Ans. (c) different number of neutrons. Atoms of same element with same atomic number but different mass number are called isotopes of that element.Which elements do not follow Pauli exclusion?Particles with an integer spin, or bosons, are not subject to the Pauli exclusion principle:...
Isotopes are different forms of elements but with differing numbers of neutrons. Adding a neutron adds mass to the element, and that can change processes of how a planet, comet, or moon is formed. Water is composed of two hydrogen (H) atoms and oneoxygen atom, H2O. Adding a neutron to...
