1. How is the modern periodic table organized? Increasing atomic number
2. What information about an atom's properties can you read from the periodic table? Metal or not metal. Does it want to gain or lose electrons
3. How are the relationships of elements in a group different from the relationships of elements in a period? a group will have similar properties A period will have different properties
4. Would you expect Strontium (Sr) to be more like potassium (K) or bromine (Br)?
potassium
5. Barium (Ba) is in Group 2. Recall that atoms in Group 1 lose one electron to form ions with a 1+ charge. What type of ion does barium form? Ba+2
Answer:
sp3 hybridization
Explanation:
Hybridization means the mixing of atomic orbitals to yield hybrid orbitals with characteristics that are different from that of the isolated atomic orbitals before the combination.
sp3 hybridization occurs when one s orbital is mixed with three p orbitals to yield four sp3 hybrid orbitals which can be used to bond to a central atom.
The central atom is then located at the center of a regular tetrahedron at a bond angle of 109°.
Answer:
Yes
Explanation:
Qualitative data deals with the properties or qualities of matter. In qualitative studies, the aim is to understand all about the structure and properties of matter.
Some qualitative methods involve the use of radiation. A typical example of such is the X-ray diffraction. XRD is a qualitative method that can reveal the internal structure of a molecule as well as arrangement of atoms which are not hydrogen.
Also radiation is useful in quantitative measurements such as atomic absorption spectroscopy, spectrophotometry, etc.
