Asample of matter is at extreme temperatures with particles moving so quickly that their collisions release electrons from the atoms. this creates a mixture of electrons and positively charged ions with high kinetic energy. what phase of matter does this describe?

The phase of matter will be known as the forth phase of matter, plasma.

There are 4 phases of matters:

Hence according to the question description and given above matter phases, the phase of that sample will be plasma.

The phase of matter will be known as the forth phase of matter, plasma

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
