Ar-39 has 21 neutrons
Ar-40 has 22 neutrons
Mendeleev's table was arranged by atomic mass and the periodic table is arranged by protons (atomic number).
The periodic table contain only chemical elements, not compounds or mixtures.
In chemistry, none! the period table does not exist one can only find the periodic table although the rows of the periodic table are called periods or series. !
what is difference between simple harmonic motion and vibratory motion?
FOR THE SIZEthe elements on the periodic tabledecreases across the periodand increases down the groupFOR THE ELECTRON DIFFERENCEFor the first 20 elementacross the period the difference between two closes element is +1 eletron or -1 eletrondown the group the difference between two closes element is +8 eletron or -8 eletron
The difference between simple harmonic motion and harmonic motion is SHM is a periodic motion.
The difference between a period and a group is that:A periodic is a horizontal row of elements in the periodic table, which simply means the column of the periodic table.A group is a vertical row of elements in the periodic table, which simply means the row of the periodic table.
periodic takes place on an irregular schedule where perpetual is a constant state of inventory
The periodic table contain only chemical elements, not compounds or mixtures.
Mendeleev's table was arranged by atomic mass and the periodic table is arranged by protons (atomic number).
Periodic changes are those changes that repeat themselves at frequent intervals of time. Non periodic changes are those changes that do not repeat themselves at regular intervals of time
the difference between groups (also known as families) and periods is: a group is a column and a period goes across the table remember that
A phase difference between two periodic signals is the time difference between two corresponding points on each signal. This time difference is usually measured in degrees or radians, but can be given as a unit of time as well.
In chemistry, none! the period table does not exist one can only find the periodic table although the rows of the periodic table are called periods or series. !
cesium and fluorine
what is difference between simple harmonic motion and vibratory motion?
Oscillatory motion is also called vibratory motion while periodic motion is a motion which is repeat itself after a specific interval. Periodic motion may be rotatory or vibratory.
