The answer is na sodium, bromine
The answer is covalent bonding feel free to message me if you want to understand why this is the correct answer :)
Ionization energy increases from left to right in the row and from bottom to top in a column. Also as we get closer to the nucleus it would be harder to take electrons out. B (atomic #5) has 2 layers of electron 2 and 3 atom in each layer. P has 15 so it would be 2,8 and 5 respectively. Ca is 20 so 2,8,8,2 and Zn is 30 and it would be 2,18,8,2.
For energy between second and third ionization we are looking at taking out the 3rd electron. B already has 3 electron in the first layer so its easy to take them all. P has 5 in the last layer so again easy. But when we look at Ca and Zn after the 2nd electron (in the last layer) we should change the layer go one layer inside. So this needs more energy. To pick between Zn and Ca (they are in the same row) I mentioned earlier that in one row as we go to the right ionization energy increases so the answer is Zn.
Particles in a solid state can only vibrate. In a liquid state, they slide against each other. And in a gas state, they move freely, bouncing and bumping into each other.
Answer:
Its images are brighter and clearer than other telescopes.
Explanation:
<em>For a telescope with large aperture, the correct answer would be that its images are brighter and clearer than those of other telescopes.</em>
The aperture of a telescope is a measure of the diameter of the optical instrument used in the telescope. The instrument could be a lens or a mirror.
<u>The larger the aperture of an optical instrument of a telescope, the more the amount of light that gets to the telescope and thus, the brighter and clearer the image taken by the telescope would be.</u>
