Most of an atom is empty space. If an atom were about as big as a baseball stadium, the nucleus would be the size of a pea in the very center and the electrons would be somewhere on the outside edge.What makes an atom of gold different from an atom of iron is the number of ...
What defines a specific type of Atom ? Continuing use of sodium as an example, what makes a sodium atom, a sodium atom ? Could another type of atom just happen to have 11 protons, 11 electrons and 12 neutrons ? No. The number of protons = the 'Atomic Number', which is sometimes ref...
If an atom gains or loses neutrons, it remains the same element but becomes an isotope of that element. Different isotopes are identified by appending M to the upper left corner of the abbreviation for that element. For example,14C is an isotope of carbon (Z = 6) that has eight neutrons...
835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that...
What causes an isotope to be radioactive? What makes an atom radioactive? How fast does a radioactive isotope decay? What isotope does americium-241 turn into after alpha decay? Explore our homework questions and answers library Search
The electrons in an atom are attracted to the protons in the nucleus by the electromagnetic force. Electrons can escape from their orbit, but only in response to an external source of energy being applied. The closer orbit of the electron to the nucleus, the greater the attractive force; hen...
Structure Of The Atom: Our current model of the atom can be broken down into three constituents parts – protons, neutron, and electrons. Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net ch...
zircon crystals may form multiple crystal layers, with each layer recording the isotopic age of an event, thus tracing the progress of the a quantity of metamorphic occasions. All elements on the Periodic Table of Elements (see Chapter 3) include isotopes. An isotope is an atom of a component...
What does an atom consist of? What are the eons in which the oxygen appeared in the atmosphere occurred? What is water made of? Select the correct answer. Which of the following elements makes up the majority of Earth's atmosphere? a. Oxygen b. Hydrogen c. Argon d. Nitrogen ...
What element makes glowing signs? What chemical element is Sb? What synthetic elements are unstable? Where do elements come from? What are the types of native element minerals? What one characteristic of an atom determines what type of element it is?
