D. The periodic table of the elements places the elements according to their atomic number, electronic configuration and chemical properties. Thus, depending on the location of an element in the periodic table, we can guess its electronic configuration and more importantly, its properties.
What can predict about an element from its position in the periodic table?
An element’s location in the periodic table is largely dependent on its electrons; the number of valence shell electrons determines its group, and the type of orbital in which the valence electrons lie in determines the element’s block.
What are three things that the periodic table can tell you about an element?
The periodic table tells us:
- Mass.
- Common charge.
- Number of Protons, Neutrons, and Electrons.
- Class/Period (reaction characteristics and element properties)
- Valence Electrons.
- Group.
How do you predict elements?
The Periodic Table can predict the properties of new elements, because it organizes the elements according to their atomic numbers. Creating new elements is not a simple process. Scientists use a particle accelerator to smash light atoms into a thin metallic foil that contains heavier atoms.
Can you predict the properties of elements and compounds?
Can you predict the properties of a compound by knowing the properties of the elements that make up the compound? No, the properties of a compound are usually different from the properties of the elements that make up the compound.
What four things are shown on a periodic table?
Explanation: Most periodic tables give at least the name, symbol, atomic number, and relative atomic mass (atomic weight) for each element. Occasionally you’ll come across one that gives the symbol but not the name.
How do you predict the period and group of an element?
The group of an element is predicted from the number of electrons in the valence shell or/and penultimate shell as follows: a)For s block elements ,group number is equal to the number of valence electrons. b) For p block elements ,group number is equal to 10+number of electrons in the valence shell.
What can you find in a periodic table?
The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, oganesson. The atomic number of an element is the number of protons in the nucleus of an atom of that element.
How can the position of elements on the periodic table be used to predict how they react with other elements?
Thus, the columns of the periodic table reflect the number of electrons found in each element’s valence shell, which in turn determines how the element will react.
How do the position of elements in the periodic table help you to predict its chemical properties explain with an example?
Explanation: Elements in the same group have the electronic structures and fall below each other. All the elements in the same group have the same number of electrons in its last shell, hence, the behave in a similar chemical way because it is the outermost electrons that take part in chemical reactions.
Can you predict the location of an elements based on its configuration?
You can get an exact location if you add up all of the electrons in the electron configuration(given it is a ground state atom(same amount of Electrons as Protons))then you will be able to get an exact location on where on the periodic table that element goes.
What are some examples of elements How do you know they are elements?
An element is a pure substance that is made from a single type of atom. Elements are the building blocks for all the rest of the matter in the world. Examples of elements include iron, oxygen, hydrogen, gold, and helium. An important number in an element is the atomic number.
How do you think scientists are able to predict that certain elements could be made when the elements do not occur naturally?
When a heavy element disintegrates, or decays, it gives off a radiation signature that can be used to prove that it existed. … Scientists create heavy elements by bombarding two lighter elements that together add up to the mass of the desired new element. One of the elements is stationary and thus called the target.
What properties of elements are predictable within rows?
Properties of elements repeat in a predictable way when atomic numbers are used to arrange elements into groups. The elements in a group have similar electron configurations, which determines its chemical properties. This pattern of repeating properties is called the periodic law.
