Which of these are examples of decomposition reactions 1 2no n2 o2 2 2k br2 2kbr 3 h2 cl2 2hcl 4 2pocl3 2pcl3 o2?
1 (fully) and 4 (only partial) are decomposition reactions.
What is outer shell electrons do group 1 elements?
i guess you mean that the group 1 elements usually lose a electron in order to become stable because the outermost of the group 1 elements have only one valence electron and it is easy to lose one than to gain seven.
What is another name for alkali metals?
Group 1 Metals
What group is k in and what is the name of the elements?
Potassium is in group 1 and the group elements are hydrogen, lithium, sodium, potassium, rubidium, cesium, francium
Which group is more reactive on the periodic table group 1 or 2?
Group 1 elements are more reactive than that of group 2 elements.
What happens when group 1 elements are placed with air?
Violent oxidation reactions.

Is oxygen given off when group 1 elements react with water?
No, oxygen is not given off when group 1 elements react with water. Instead, these reactions typically result in the formation of hydroxide ions and hydrogen gas.
Which group of elements in the periodic table is known as the alkali?
The group of elements in the periodic table known as the alkali metals is group 1, which includes lithium, sodium, potassium, rubidium, cesium, and francium. These elements are highly reactive and typically form ionic compounds in reactions.
What is outer shell electrons do group 1 elements?
i guess you mean that the group 1 elements usually lose a electron in order to become stable because the outermost of the group 1 elements have only one valence electron and it is easy to lose one than to gain seven.
How many moles of atoms are in 44.0 Br2?
44.0 grams Br2 ? 44.0 grams Br2 (1 mole Br2/159.8 grams)(6.022 X 10^23/1 mole Br2)(1 mole Br2 atoms/6.022 X 10^23) = 0.275 moles of Br2 atoms
What is another name for alkali metals?
Group 1 Metals
Oxidation number for first 20 elements?
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.
What is the oxidation number for all elements in this group?
Group 1 elements have an oxidation number of +1.
What group is k in and what is the name of the elements?
Potassium is in group 1 and the group elements are hydrogen, lithium, sodium, potassium, rubidium, cesium, francium
What is the name of the family of elements in Group IA 1?
Group IA or group 1 elements are known as alkali metals.
