They tell you how many molecules of two or more compounds combine to form other molecules. The equation can, but will not always, tell you if the reaction requires heat or gives off heat (endothermic/exothermic), whether or not a catalyst is required.

What element has 61 protons?
The element Silver has 61 neutrons. Its symbol on the Periodic Table is 'Ag'.
What compounds is nickel found in?
A nickel is a US coin with a face value of 5 cents. It's an alloy rather than a compound, made of 25% nickel and 75% copper. Nickel is a metal, an element with an atomic number of 28 and an atomic weight of 58.6934.
What three things does the atomic number of an element tell us?
It tells us that:How many protons the atom hasHow many electrons the atom has (when it is in non-excited, ground state)It identifies the element itself
What does the atomic weight of an element tell us about it?
The atomic number tells us the number of protons in the nucleus of an atom. The atomic mass tells us the sum of the protons and neutrons in a nucleus.The atomic weight (not mass) of a chemical element is the ratio between the average mass of the atoms of this element to 1/12 from the atomic mass of carbon-12.The atomic mass is a term applied only to specific isotopes; the unit is the same as above. Is a value denoting the total mass of all the protons, neutrons, and electrons in an isotope.The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.The atomic number, on the other hand, tells us how many protons are in the nucleus of an atom.IUPAC publish periodically tables of atomic weights - the last edition is from 2009-2010.For the atomic masses of isotopes the last published edition is The AME 2003 atomic mass evaluation, edited by Audi, Wapstra and Thibault.
What does the number of protons in an atom also tell you?
The number of protons in the nucleus of an atom tell you which element you are dealing with. It is the number of protons in an atomic nucleus that determines the elemental identity. Only that. The atomic number of an element is the number of protons you will find in the nucleus of every atom of that element, regardless of the number of neutrons or electrons involved.
What does the atomic number tell us about an element?
The atomic number is the number of protons in the nucleus.The Atomic Number of an element helps us to locate that particuarler element on the Periodic Table of Elements.
What does an element's atomic mass tell us about the atoms that make up that element?
atomic mass is the no. of protons+no. of nuetron
What does the atomic number tell us about calcium?
Calcium is a metal element. Atomic number of it is 20.
What does the atomic number number tell us about an elements?
The atomic number is the number of protons in the nucleus.The Atomic Number of an element helps us to locate that particuarler element on the Periodic Table of Elements.
What are the word to be used to fill these empty spaces an element's atomic ----- tells us how ----- each atom is?

What is the lightest element of the ones below with an atomic symbol that is also a US state postal code?
Aluminum (AL)
What does the atomic number tell us about an atoms?
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.
What does an element's atomic number tell us?
The atomic number is the number of protons that the element has.
What does the atomic number of the atom tell us?
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.
What element has 61 protons?
The element Silver has 61 neutrons. Its symbol on the Periodic Table is 'Ag'.
What the atomic number tell us?
The atomic number of an atom is the number of protons in the nucleus of an atom. The number of protons determines the identity of an element and its properties. Hope this helps :3
Is magnesium a compound made up of 2 separate elements?
Magnesium is an element so is not made of other elements. An atomic physicist might tell us that Magnesium could be split into lighter components in a nuclear reactor but I think Magnesium is itself too light for that to be possible. from Beano in the UK
