Answer:
The metallic elements have more metallic characteristcis.
Explanation:
- Metallic character is the name given to a set of common properties shared by the metallic elements.
- Metallic luster, high density, high electric and thermal conductivity are some physical properties associated with metallic characters.
- Malleability and ductility is also an important metallic characteristic.
- Generally the metals are hard and dense.
- The elements on the left hand side of the periodic table show metallic characteristics except hydrogen.
Answer:
The Atomic Number
Explanation:
The X would be the Atomic Number or amount of protons sorrounding the nucleus of that atom.
Answer:
Take a look at the attachment below
Explanation:
Take a look at the periodic table. As you can see, Rubidium is the closest element to Cesium, and happens to have the closest boiling point to Cesium, with only a difference of about 30 degrees.
Respectively, you would think that fluorine should have the least similarity to Cesium with respect to it's boiling point, considering it is the farthest away from the element out of the 4 given. This is not an actual rule, there are no fixed trends of boiling points in the periodic table, there are some but overall the trends vary. However in this case fluorine does have the least similarity to Cesium with respect to it's boiling point, a difference of about 1,546.6 degrees.

The percent error in the initial measurement would be 6.47%
<h3>Percent Error</h3>
Percent error in any measurement is mathematically given as:
absolute error/true measurement x 100%
In this case;
True measurement = 1.34 qt
Absolute Error = 1.34 - 1.25
= 0.09 qt
Percent error = 0.09/1.34 x 100%
= 6.47%
