How many protons are in a pizza?
According to LiveStrong, a typical slice of thin-crust cheese pizza contains 230 calories while a slice of thick-crust cheese pizza contains 312 calories.
What particles make up an atom gizmo?
Atoms are tiny particles of matter that are made up of three particles: protons, neutrons, and electrons. The Element Builder Gizmo ™ shows an atom with a single proton. The proton is located in the center of the atom, called the nucleus.
How can you calculate the number of neutrons N in an atom gizmo?
To calculate the number of neutrons in the nucleus of an atom is simple. You take the atomic, or proton number of the element, and you subtract it from the element’s mass number.
How many electrons are in a neutral atom of lithium gizmo?
Create a lithium atom (3 protons, 4 neutrons, 3 electrons ).

How much sodium is in a slice of cheese pizza?
A slice of pizza can weigh in anywhere from 600 to 1500 mg of sodium per slice!
What is the heaviest stable isotope?
Examples of elements with doubly magic nuclei are 42He, with 2 protons and 2 neutrons, and 20882Pb, with 82 protons and 126 neutrons, which is the heaviest known stable isotope of any element.
What does the top number equal gizmo?
The top number is the mass number (A). The mass number is the sum of the protons and neutrons.
What particles make up an atom?
Atoms are constructed of two types of elementary particles: electrons and quarks. Electrons occupy a space that surrounds an atom’s nucleus. Each electron has an electrical charge of -1. Quarks make up protons and neutrons, which, in turn, make up an atom’s nucleus.
How can you determine the number of neutrons?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
What charge does a neutron have?
Proton—positive; electron—negative; neutron —no charge. The charge on the proton and electron are exactly the same size but opposite.
What is the formula to solve for the neutron?
The mass number is the sum of protons and neutrons in the nucleus. The atomic number is the number of protons. Therefore, you can subtract the atomic number from the mass number to find the number of neutrons.
How many valence electrons are in lithium?
Lithium has a single electron in the second principal energy level and so we say that lithium has one valence electron.
How are electrons arranged gizmo?
Electrons are arranged in orbits called energy levels. The Gizmo shows all of the first two energy levels but only part of the third energy level. A.
