What is true of elements in a period?
Like PERIODic table.). All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.
What common characteristic is generally shared by the elements at the center of a period?
Answer: The common characteristic that is shareed by the elements found at the center of a period would be that they are the least reactive species. Having lower value of electronegativity, there is less ionization of the atoms which would also contribute to less reactivity.
What is a common characteristic of the transition elements?
The common characteristic of the transition elements would be that the next to outermost electron shell begins to fill up. Transition metals are the elements that have partially filled d orbitals.
What is a common characteristic of transitions elements the next to outermost electron shell begins to fill up the next to outermost shell is always complete?
The next to outermost electron shell begins to fill up. What is a common characteristic of the transitions elements? -The elements in each group have similar chemical properties. -Each member of the group has the identical electron configuration in the outer shell.
What is the maximum number of electrons that will be in the 1st valence shell?
two
What are some characteristics of transition metals?
The transition metals have the following physical properties in common:
- they are good conductors of heat and electricity.
- they can be hammered or bent into shape easily.
- they have high melting points (but mercury is a liquid at room temperature)
- they are usually hard and tough.
- they have high densities.
Why Copper is a transition element and zinc is not?
When it forms ions, it always loses the 3 outer electrons and ends up with an argon structure. The Sc3+ ion has no d electrons and so doesn’t meet the definition. Zinc has the electronic structure [Ar] 3d104s2. Copper is definitely a transition metal because the Cu2+ ion has an incomplete d level.
Is Zn a metal or nonmetal?
Zinc (Zn), chemical element, a low-melting metal of Group 12 (IIb, or zinc group) of the periodic table, that is essential to life and is one of the most widely used metals. Zinc is of considerable commercial importance.
Why zinc is metal?
Most zinc is used to galvanise other metals, such as iron, to prevent rusting. Galvanised steel is used for car bodies, street lamp posts, safety barriers and suspension bridges. Large quantities of zinc are used to produce die-castings, which are important in the automobile, electrical and hardware industries.
