The chemical reactivity of transition metals is generally less than that of metals to its left (group 1 and group 2 metals). However, transition metals can exhibit various oxidation states and hence form more number of compounds than group 1 and group 2 elements.

Why are elements grouped together on the periodic table?
They are organized according to atomic number, which refers to the number of protons that the nucleus contains. They are organized into columns, called families by the number of electrons in the orbitals. The farther down you go, the more elements, because there are more orbitals on higher energy levels. Also, the elements to the right of the line on the periodic table are nonmetals, the ones on the line are semimetals, and the ones to the left of the line are metals.
What two properties is the modern periodic table based on?
The group proposing that elements within the same group have the same electron configurations in their valence shell, which is the most important factor in accounting for their similar properties. Elements in the same group also show patterns in their atomic radius, ionization energy, and electronegativity. From top to bottom in a group, the atomic radii of the elements increase. Since there are more filled energy levels, valence electrons are found farther from the nucleus. From the top, each successive element has a lower ionization energy because it is easier to remove an electron since the atoms are less tightly bound. Similarly, a group will also see a top to bottom decrease in electronegativity due to an increasing distance between valence electrons and the nucleus. While, the elements in the same period show trends in atomic radius, ionization energy, electron affinity, and electronegativity. Moving left to right across a period, atomic radius usually decreases. This occurs because each successive element has an added proton and electron which causes the electron to be drawn closer to the nucleus. This decrease in atomic radius also causes the ionization energy to increase when moving from left to right across a period. The more tightly bound an element is, the more energy is required to remove an electron. Similarly, electronegativity will increase in the same manner as ionization energy because of the amount of pull that is exerted on the electrons by the nucleus. Electron affinity also shows a slight trend across a period. Metals (left side of a period) generally have a lower electron affinity than nonmetals (right side of a period) with the exception of the noble gases.
Which elements have one valence electron?
In addition to hydrogen, all elements in Group I of the periodic table have one valence electron. They are lithium, sodium, potassium, rubidium, cesium, and francium. The farther you move right on the periodic table the more valence electrons. For example, elements in Group VII have 8 valence electrons except helium.
Electrons farther from the nucleus are said to be of?
"higher energy"
Describe the trend in nonmetallic property of the elements in group 16?
The name of the group is the oxygen family. The valence number for elements in that group are -2. (gain or share two electrons) Oxygen, sulfur and selenium are nonmetals. Tellurium and Polonium are metalloids.
Why do elements in a group have similar properties?
As you pass from left to right and from one line to the next line below it, you are incrreasing the atomic number of each element, one proton at a time. As the protons increase, so do the electrons, and they fill up shells and start new shells. Chemical properties depend mainly on the number of electrons in the outermost shell (for transition state elements it doesn't work exactly by shells, since in the heavier elements it is possible for an electron in an inner shell to nonetheless be farther from the nucleus than some electrons in the outer shell, but that is an added complication). So, elements in the same group have the same number of outer, or valance electrons as they are known.
Which elements in the periodic table are metalloids or have semimetallic properties?
The elements that are commonly recognized as metalloids or semimetals are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te). These elements exhibit properties of both metals and nonmetals, such as being good conductors of electricity but also brittle and less malleable.
How do the properties of groups 3 through 12 compare with the elements left and right of the transition metals?
Elements from Group 3 to 12 are called Transition Elements. These elements are heavy metals. They lie between the strongly eloctropositive elements to their right and the electronegative elements ( non-metals) to their left.These metals mainly have 2 valence electronswith the metallic character decreasing from left to right of their period.

How do you use a number line to compare two integers?
Whatever is farther to the right is greater.
How do the number of electrons change across the period of elements?
they get more electrons the farther right the get
What is size in art?
when the elements in the drawing or painting decreases. things appear smaller as they get farther
What is diminishing size in art?
when the elements in the drawing or painting decreases. things appear smaller as they get farther
Who does the latitude of most of Europe and Russia compare with that of the US?
europe and rusiia are double the size of the us
What elements have low electronegativity?
The elements with low electronegativity are the metals, specifically the alkali metals and alkali earth metals. The elements further to the left of the periodic table will have lower electronegativity than those farther to the right.
