Chlorine has a charge -1. It means that X is +2 so that the formula is XCl2. Group 2 is the correct answer.

Answer;

Group 2

Explanation;

-Elements in group 2 (alkaline earth metals) have a 2 valence electrons (two electrons in the outermost energy shell). Which means that for these elements to achieve an octet configuration, they will have to loose two electrons. Therefore; element X has a valency electrons, it reacts chlorine to form a compound (XCl2), since chlorine has a valency of 1.

hi:) anyone able to explain no.2 of what happens to particles of a solid that is heated until it melts? I don’t understand it. T
Viefleur [7K]
In a solid the particles are all really close together and stuck like that. As the solid melts and becomes a liquid the particles spread out. A solid won’t easily change its shape because the particles are bound together but in a liquid the shape is more fluid, take water when you pour it into a container it will change to fit the shape of a container this is because the particles aren’t as close and can move around. The particles of a solid change when it melts because it is changing states to a liquid.

What do measurements of the mass of the Milky Way indicate?
miv72 [106K]

<span>That the mass is far lesser and distributed mistakenly, as compared to what the orbits of stars declare it should be. Stars orbit more rapidly than the mass would predict, particularly out toward the galactic edge. This means that there is more mass than has been measured, and that it is spread out in a huge cloud around the galaxy. This is one of the reasons why scientists believe that dark matter exists.</span>

What is one important role that ocean waters have in heating Earth?
Talja [164]

Answer:

Ocean temperature plays an important role in the Earth's climate system—particularly sea surface temperature (see the Sea Surface Temperature indicator)—because heat from ocean surface waters provides energy for storms and thereby influences weather patterns.
