The search is now on for an element with atomic number 119. Based on periodic trendswhich the following would most true of this element? A . it would be a nonmetal

B. would be placed into Period 7

C. would have a lull valence shel ) of electrons

D .would most likely cations when it reacts

kylee is the best ever in the whole world

Explanation:

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

particle   p is an electron and particle q is a neutron
