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
<span>Valence electrons are important because these are the only electrons involved with an atom's chemical reactivity.</span>
Answer:
Li(s) + H20(l) --> LiOH(aq) + H(g)
Explanation:
it is already balanced
Answer:
Explanation:
A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

Answer:
1.80 × 10²⁴ Molecules of Sucrose
Solution:
Number of Moles and Number of Particles (molecules in given case) are related to each other as,
Moles = Number of Molecules ÷ 6.022 × 10²³
Solving for Number of Molecules,
Number of Molecules = Moles × 6.022 × 10²³
Data Given;
Moles = 3 moles
Putting values in eq,
Number of Molecules = 3 mol × 6.022 × 10²³
Number of Molecules = 1.80 × 10²⁴ Molecules
