What information does the group tell you about the atomic structure of an atom?
Explanation: The number of outer shell electrons determines the group number of the element. The number of occupied principle quantum shells (energy levels) determines the period of the element. The proton number determines the element itself and its position.
Why is knowing atomic structure important?
By learning about atomic structure, we can find out how atoms combine and form many compunds. By learning about atomic structure, we can find out how atoms collide. By learning about atomic structure, we can find out why atoms do not have mass.
What determines the structure of an element?
Atoms consist of three basic particles: protons, electrons, and neutrons. This can be determined using the atomic number and the mass number of the element (see the concept on atomic numbers and mass numbers). Structure of an atom: Elements, such as helium, depicted here, are made up of atoms.
What kinds of information about the atomic structure of an element can you learn from the periodic table?
Within each element square, information on the element’s symbol, atomic number, atomic mass, electronegativity, electron configuration, and valence numbers can be found.
What can you determine about the atomic structure of an element if you know the atomic number of the element and mass number of its isotope?
What can you determine about the atomic structure of an element if you know the atomic number of the element and mass numbers of its isotope? THe atomic number of an element is the same number of protons and electrons the element has.
What are the uses of the elements found in the periodic table of elements?
| ELEMENT | USES | |
|---|---|---|
| 1) | Aluminum | A light metal used in making airplanes, buildings, pots & pans, etc. |
| 2) | Bromine | Used in photography, medicines, insecticides, etc. |
| 3) | Calcium | A soft, metallic chemical element found in limestone, marble, chalk, etc. |
| 4) | Carbon | Found in coal, oil gas, living things, & inks |
What is one thing that determines the identity of an atom?
Explanation: The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.
When using the periodic table the easiest way to determine how many protons exist in an atom of an element is to look at what?
Locate the element’s atomic number. The atomic number is located above the element symbol, in the upper left-hand corner of the square. The atomic number will tell you how many protons make up a single atom of an element. For example, boron (B) has an atomic number of 5, therefore it has 5 protons.
How do you describe the atomic structure?
Atomic structure refers to the structure of an atom comprising a nucleus (centre) in which the protons (positively charged) and neutrons (neutral) are present. The negatively charged particles called electrons revolve around the centre of the nucleus.
What do you mean by atomic structure?
The definition of atomic structure is the positively charged nucleus and the negatively charged electrons circling around it, within an atom. An example of atomic structure is what gives energy to atoms and then to molecules. noun.
What does the atomic structure of an element depend on?
The atomic structure of an element also takes into account the mass of the atom as well as the charge of the atom. The arrangement of electrons in an atom referred to the orbital definition of the location of these electrons in an atom. They are arranged depending on the potential energy in various orbits.
How did the discovery of particles inside atoms lead to better understanding?
The discovery of particles inside atoms led to a better understanding of chemical species, these particles inside the atoms are called subatomic particles. The discovery of various subatomic particles is as follows: The English chemist Sir Joseph John Thomson put forth his model describing the atomic structure in the early 1900s.
What keeps atoms from occupying the same place in an atom?
This can be attributed to the fact that the electrons present in the atom are negatively charged and hence they cause repulsion to one another. This is what keeps the atoms from occupying the same place. The mass number of an atom, as well as the atomic number of an atom, also determines the atomic structure.
How are electrons arranged in an atom?
The electrons in an atom are arranged in a very significant way. The electrons are found in the electron shells outside the nucleus. The electrons are negatively charged particles of an atom. The atomic structure of an element also takes into account the mass of the atom as well as the charge of the atom.
