The atomic number of an atom indicates the number of?
The atomic number is the number of protons in the atom. In the case of a neutral atom (as opposed to an ion), the atomic number is also equal to the total number of electrons.
A periodic pattern appears in the physical and chemical properties of the elements when they are arranged in order of increasing atomic number what is this?
This periodic pattern is known as the periodic table. It allows us to predict the properties of elements based on their position in the table. The arrangement is based on the number of protons in the nucleus of each element, which determines its chemical behavior.
What two things does a chemical formula tell us about a compound?
the actual number of atoms in a molecule
What is the atomic number on a table that tells us how many of what are in an atom of the element?
The atomic number of an elemnt tells you how many protons are in the nucleus and therefore how many electrons thare are in a neutral atom. The mass number is the toal of protons and neutrons.
What element has a atomic mass of 39.9?
The atomic number is the count of how many protons an atom has in its nucleus (and therefor also the count of how many electrons the neutral atom possesses). The atomic number us unique for each element and positions the element in the periodic table. The element with atomic number 39 is Yttrium (Y).
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 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 the atomic number tell us and where is it?
up there
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 tell us?
The atomic number tells us the number of protons in the nucleus of an atom. It determines the element's identity and its place on the periodic table. Elements with different atomic numbers have different chemical properties.
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 dose the atomic number tell us?
the # of protons
What four things does a periodic table tell us?
The periodic table tells us:The elements atomic massThe elements atomic numberIf the element is a gas, metal, etc.How many protons, electrons and neutrons an element hasThe name of the elementWhich elements could have similar properties (nearby in the chart)(Oops that was already six things (but some of them depend on the others)
What does the period number tell us about the element?
For elements it's the atomic number not the "Period Number." This number tells you how many protons a single atom of that element has in its nucleus. The "period number" is a dimensionless quantity used in fluid dynamics.
What are the orientation of elements in the peridoc table tell us the arrangement of the what?
The periodic table is in order of atomic mass
What does the atomic mass tell us?
it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
What does the atomic number tell us about nitrogen?
The nitrogen has 7 protons. your welcome!
