because its a metalloid and the rest are all metals

What pattern in atomic size occurs in the periodic table?
In the periodic table, the atomic size increases with every period due to addition of an extra shell. The atomic size decreases with every group since no. of electrons and protons are increased with every group across a period leading to extra electrostatic force of attraction between electrons and the nucleus and thus shrinking the size of the atom.
Does the periodic table explain the shell model or does the shell model explain the periodic table?
The shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.
How many valence electrons are present in an atom of bromine in the ground state?
5 valence electrons exist in bromine period, at ground state bromine has 3 valence electrons
Why is chlorine in period 3?
Chlorine is in period three because that is how many outer shells it has. One period is one shell... In the First outer shell you can only hold.. 2 electrons. Second outer shell can hold 10 electrons. Third outer shell can hold 18 electron. Protons + Electrons = Atomic Number Atomic Number - Atomic Mass = Number of Neutrons in Outer Shells
How many outer shell electrons does calcium have?
The calcium atom has 2 outer shell electrons. It's configuration is: [Ar] 4s2 it also has 2 inner shell electrons
Why does boron not always continue the Period 2 pattern of reacting electrby losing ions as do beryllium and lithium?
I know your doing your chemistry homework ..............me too do your best ............
What does the sequence in each period represent in relation to electrons?
The sequence in each period represents in relation to electrons is that as you look from left to right on the periodic table, you see a pattern; an increase of the atomic number. The number of electrons equals the number of protons, and the number of protons equals the atomic number.
Should you continue HCG if you get your period?
should I continue on the HCG diet if i get my period?
How are the relationship of elements in a group different from the relationship of element in period?
Group - similar reacting properties. SIMILAR not identicalPeriod - ever increasing proton numberAnswer 2:elements in the same period have the same amount of energy levels (in which electrons orbit around the atomic nucleus)elements in the same group have the same number of valance electrons (which are found in the outer most energy level)
How can period number related to the location of valence electrons?
The period number is the same as the energy level containing the valence electrons. For example, in period 4, the valence electrons are the 4s and 4p electrons.
What does the period tell you about electrons?
The period tells you how many energy levels an atom has.
Why do properties of element change in Regular way across a period?
As atomic number increases, the number of electrons also increases except for Period 1 because it ends with a number of valence electrons with higher energy , (This pattern means that the elements within a group always have the same number of valence electrons having the result of having similar properties.)
Why do element properties change in a regular way across a period?
As atomic number increases, the number of electrons also increases except for Period 1 because it ends with a number of valence electrons with higher energy , (This pattern means that the elements within a group always have the same number of valence electrons having the result of having similar properties.)
What if you get your period while the birth control patch is one?
If you get your period while wearing the birth control patch, continue using the patch as scheduled. If this becomes a problematic pattern for you, contact your health care provider.
What element is found on period 4 and has 7 valence electrons?
Only nitrogen (but in the period 2) has 7 electrons in the neutral atom.
How is the element's period related to the number of energy levels over which its electrons are spread?
The period that the element's in is the same number of how many valence electrons (energy level of outer electrons) there are in the element...
What does the period number tell about the energy levels occupies by electrons in an atom?
the period number tells which is the highest energy level occupied by the electrons
