A laboratory is suspected to be contaminated with radiation from a radioactive material. Which of the following detection instruments can be best used to detect this radiation? (5 points) An X-ray film, because it can detect the low frequency X-rays. An X-ray film, because it can detect the low energy infrared radiation. A Geiger counter, because it can detect the high energy gamma rays. A Geiger counter, because it can detect the highly penetrating ultraviolet radiation.

i think its 100

i hope this !

ok whats the question if not i cannot you i need question and need a thing to answer

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.

idk i'm not smart
