The p-block metals are aluminum, gallium, indium, thallium, lead, tin, bismuth, and polonium. also, ununtrium, ununquadium, and ununpetium are sometimes comsidered p-block metals, although they are man-made.
The oxidation numbers for the first 20 elements in the periodic table are typically as follows: Group 1 elements: +1; Group 2 elements: +2; Group 13 elements: +3; Group 14 elements: +4 or -4; Group 15 elements: -3; Group 16 elements: -2; Group 17 elements: -1; Group 18 elements: 0. Keep in mind that oxidation numbers can vary in different compounds and contexts.
Hydrogen and carbon.
Group IA or group 1 elements are known as alkali metals.
The representative elements are usually called the main group elements or the Group A elements. They are located in the leftmost and middle sections of the periodic table, excluding the transition metals.
Mendeleev's first periodic table contained 63 elements. He left gaps for undiscovered elements and predicted their properties based on the patterns of the known elements around them. Mendeleev's table was later expanded to include more elements as they were discovered.
metals, metalloids, and nonmetals. Save ...?
Carbon, hydrogen, and oxygen.
nitrogen and oxygen
There are many elements that are contained in seawater. Some examples include magnesium, sulfur, selenium, silicon, fluorine, sodium, and chlorine.
Elements within the same group on the periodic table have similar chemical properties because they share the same number of valence electrons. This leads to comparable reactivity and bonding patterns between elements in the same group. Groups on the periodic table are arranged vertically, with elements sharing a group having the same number of electrons in their outermost shell.
the answer is complement
Hydrogen and Oxygen
elements are in the same group since they react similarly to other elements in that group.
main group elements
There is a total of 17 elements in those groups.
No. noble gases are group VIIIA or group 18 elements
Group 17 elements are called the halogens. Group 18 elements are called the noble gases.
