What is three elememts in period 3 that are lustrous and good conductors of eletricity?
Three elements in period 3 that are lustrous and good conductors of electricity are sodium, magnesium, and aluminum. These elements possess metallic properties due to their high electrical conductivity and shiny appearance.
What are the THREE properties of elements?
The main three properties of the metals are malleability (you can shape it easily), ductility (you can turn it into a wire) and conductivity (it will carry heat and electricity very well).
What do you called the arrangement of grouping elements by three?
This arrangement is called "triplets," where elements are grouped in sets of three.
Which three elements are most abundant in carbohydrates?
The three most abundant elements in carbohydrates are carbon, hydrogen, and oxygen. Carbohydrates are composed of these three elements in varying ratios.
Why did Johann dobereiner trying to order the elements?
Johann Dobereiner attempted to order the elements to find patterns and relationships between their properties. He proposed the Law of Triads, which grouped elements with similar properties into sets of three based on their atomic weights. This was an early attempt at organizing the elements before the more comprehensive periodic table was developed.
What are the top three most reactive halogen's?
Fluorine, Chlorine, and Bromine in order of decreasing activity.
What are the three metallic properties of elements?
The main three properties of the metals are malleability (you can shape it easily), ductility (you can turn it into a wire) and conductivity (it will carry heat and electricity very well).

Why are the elements in period three together?
They are placed in order of the atomic number.
What are the elements in H2SO4?
Hydrogen, sulfur, and oxygen, the three elements with the three atomic symbols shown in order in the formula.
Is decreasing a five word syllable?
It is a three syllable word.
What 3 countries are incresing in population and what 3 countries are decreasing in population?
Mexico's population is decreasing and China's population is increasing-more than the U.S.
What are the three main elements of a triangle?
The three main elements of a triangle are its three sides, three angles, and three vertices.
What are the three pairs of elements that are out of order in the periodic table in terms of their atomic masses. Why it is necessary to invert their order in the table?
The three pairs of elements that are out of order in terms of their atomic masses are iodine and tellurium, cobalt and nickel, and uranium and neptunium. It is necessary to invert their order in the table to maintain the order of increasing atomic masses within each group or period, ensuring that elements with consecutive atomic numbers also have consecutive atomic masses.
What are the three eleme?
If you mean "elements", there are not three, but over a hundred known elements.
Name the 3 major groups on the periodic table in order of their decreasing sizeWhere on the periodic table is each group located?
The 3 major groups are: # Metals - Groups 1-15 and the Inner Transitional Elements # Nonmetals - Groups 1 and 14-18 # Metalloids - Groups 13-17 (Diagonal strip of elements separating the metals from the nonmetals)
