What happens to the temperature increase the number of particles what happens to the pressure?
Increasing the temperature the number of particles remain constant and the pressure increase.
The rows going across the periodic table is known as periods and contain elements with the same number of?
Electron shells
What is three ways the periodic table arranged?
The periodic table is arranged (1) by increasing atomic number; (2) into groups of elements with similar chemical properties; (3) into periods of elements with the same number of electron shells.
What is the periodic table of elements organized by?
In the most usual modern form of a periodic table, the arrangement is by atomic number from left to right and in as many rows or periods as the number of the highest electron shell in the atom that contains at least one electron in a neutral atom. The only two elements in the first periods are at the far left and far right in columns 1 and 18, and the second and third periods skip columns from 3 through 12. In the sixth and seventh periods, the entry in column 3 is usually a footnote referring to a separate row at the bottom of the table where the atomic number sequence continues before adding an element to column 4.
What happens when U-235 emits a beta particle?
beta decay results from the transformation of a neutron in the nucleus to a proton (+ charge) and an electron (beta particle). The proton remains in the nucleus increasing the atomic number by one (mass number remains the same) while the electron is emitted as a beta particle. So, U-235 of atomic number 92 changes to Neptunium with atomic number 93. However, to my knowledge, U-235 decays by gamma not beta. U-236 decays by beta to Neptunium-236.
The periods in the Periodic Table have the same number of what?
They have the same number of electron shells.
Why are the elements on the periodic table separated into periods?
They are put into periods based on their number of electron shells.
Are periods valence electrons or electron shell?
The period tells you the valence ELECTRON SHELL (energy level). The group tells you the number of valence electrons.
What happens to the temperature increase the number of particles what happens to the pressure?
Increasing the temperature the number of particles remain constant and the pressure increase.
What is the relationship between the electron configuration of an element and the period in which that element appear in the periodic table?
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
The rows going across the periodic table is known as periods and contain elements with the same number of?
Electron shells
What is three ways the periodic table arranged?
The periodic table is arranged (1) by increasing atomic number; (2) into groups of elements with similar chemical properties; (3) into periods of elements with the same number of electron shells.
Can you describe how the reactivity of group 1 elements varies with increasing atomic number?
With increasing atomic number, the lone valence electron gets further away from the nucleus and is thus less tightly bound. It thus wants to lose the electron even more so and thus INCREASES in reactvity
What are the differences between groups and periods?
Groups consist of elements listed in the same column. These elements share similar chemical properties, such as number of valence electrons. Periods are the rows of elements. These elements do not share chemical properties, as periods are organized by increasing atomic number (number of protons).
What happens to the electron configuration as the atomic number increases?
the elctron configuration increases
When you read the periodic table horizontally what happens to the atomic number?
It is increasing consecutively.
What is the table given rules?
In order of increasing atomic number. Periods tell energy levels. Groups tell number of valence electrons. -PainRain
