Answer:

A and B

Explanation:

A: The discovery of x- rays is a scientific discovery that led to X-ray machines which is technology.

B: Finding out that massive amounts of energy can be released by splitting the nucleus of an atom was the discovery and it led to nuclear power plants.

Satellites helping scientists map the earth doesn't really have an example of science. It just says that Satellites help scientists, and satellites are technology.

Robotic machines are also technology. Robots assisting doctors in surgery is technology helping people not science influencing technology.

So A and B would be the answers.

Hope this helps :)

Answer:

Three hydrogen atoms to form PH₃.

Explanation:

Hello!

In this case, since the elements belonging to the nitrogen family (N, P, As, Sb and Bi) show five valence electrons, because there are five electrons at their outer shell, it is clear that if phosphorous bonds with hydrogen, it is going to require the same amount of oxygen atoms (3) because elements having five valence electrons need 3 bonds in order to attain the octet (5+3=8).

Therefore the compound would be:

$PH_3$
