isotope - one of two or more atoms with the same atomic number but with different numbers of neutrons monad - (chemistry) an atom having a valence of one chemical element, element - any of the more than 100 known substances (of which 92 occur naturally) that cannot be separated into simp...
Isotopes 8. Isotopes A. Isotopes are atoms of the same element that have different numbers of neutrons and different mass numbers. B. Isotopes of an element have the same atomic number but different mass numbers because they have different numbers of neutrons. Isotopes Ex. 1) Oxygen has 8 pr...
5. Helium atom has an atomic mass of 4 u and two protons in its nucleus. How many neutrons does it have? Ans:The atomic mass of an atom is the sum of masses of protons and neutrons present in its nucleus. Given that the mass of the helium atom is 4 u and two protons present in...
Identify the part of the atom that most determines the chemical properties of the atom. A variation of an element, has different number of neutrons, but same number of protons and electrons, is called what? Atoms with the same n...
Atoms containing the same number of protons but different numbers of neutrons represent different forms, or isotopes, of the same element. The Electrons Surrounding the nucleus of an atom are its electrons; for a neutral atom, the number of electrons is equal to the atomic number. The ...
Isotopes Isotopes of an element have the same number of protons, but different numbers of neutrons. Isotopes of an element have the same number of protons, but different numbers of neutrons. There can be many isotopes of the same element. There can be many isotopes of the same element....
Both the protons and neutrons reside in the nucleus. Protons have a postive (+) charge, neutrons have no charge --they are neutral. Electrons reside in orbitals around the nucleus. They have a negative charge (-). It is the number of protons that determines the atomic number, e.g., H...
Atoms are the purest form of matter. They consist of protons, neutrons, and electrons. The periodic table lists all of the different types of atoms that are known to exist and are known as elements. Answer and Explanation: An atom that has more protons than electrons is called a cation. ...
Properties of Atoms All atom have a neutral charge because the number of positive protons equals the number of neg electrons.: In nucleus of atom are protons that have a positive charge (p+) and neutrons that have a neutral charge. Outside of the nucleus are the electrons. Electrons have ...
there are protons (positive charge) and neutrons (no charge). These are where the vast majority of the weight is and will determine what type of atom this is. Electrons (negatively charged) orbit relatively far away from the nucleus and are responsible for most of the chemistry between molecu...
