well its takes for ever to figure out
They have the same number of valence electrons.
Helium has 2 valence electrons like those of group 2 elements, but is place along with the noble gases as it has completely filled valence orbitals.
they are all grouped by the boron family
the elements are in a group
Elements in the same column belong to the same family. The elements in the family also have the same number of valence electrons.
all elements are listed in a verticle column but each column indicates a family such as group seven, the halogens, or a group of similar elements such as the oxygen family or nitrogen family.
Antimony and bismuth may be considered similar elements.
H2O. Notice the presence of two elements, H and O. Each of the other three is an element.
elements in a group have the same number of valence electrons. The number of shells present increases as we move down a group.
Elements in the same column belong to the same family. The elements in the family also have the same number of valence electrons.
Each family of elements has its own set of characteristics that each of the elements possess.
alkaline metals
What they have in common is that the ones of the same family is that they all have a close amount of protons.
all elements are listed in a verticle column but each column indicates a family such as group seven, the halogens, or a group of similar elements such as the oxygen family or nitrogen family.
The elements in the 8 main columns of the Pperiodic Table are called Groups. Groups 1 and 2 are separated from Groups 3 to 8 by a block of elements called the Transition Series and the columns in this series have no specific names.
Antimony and bismuth may be considered similar elements.
A "family" of elements means the vertical columns in the periodic table. If you look above the periodic table, there will be numbers for each row, numbered from 1 to 18. Each "family" is a column.
H2O. Notice the presence of two elements, H and O. Each of the other three is an element.
the number of orbitals increases by one for each period.
elements in a group have the same number of valence electrons. The number of shells present increases as we move down a group.
Reactivity is associated with position. Chemical properties of element can be determined from its position.
