True I think is the answer
Remember that the:
1. Vertical columns are groups and families
2. Horizontal columns are periods
3. Period 1 has 2 e-, 2 has 8 e-, 3 has 8 e-, and 4 has 18 e-
3.The number on top of the groups/families shows what group it is on (ex. 1A, 2A, 3B, 4B, etc) and the number on top of that indicates the number of the same thing (what group it is)
⇒ ex. 1A has 1 val e-. 2A has 2 val e-. 3A has 3 val e- ( and rest goes up until 8A). Note: I skipped the transitions metals since they don't have accurate amount of val e-.
4. Know which is the mass number, atomic number, symbol, or name.
5. Where the metals, non- metals, and metalloids are located.
6. Elements on the same groups have similar properties.
7. The first group is Akali Metals and are very unstable and very reactive
8. Second group is Akaline Earth Metals
9. The middle, groups 3-12 are Transition Metal
10. Group 13 is the Boron Family.
11. Group 14 is the Carbon Family
12. Group 15 is the Nitrogen Family
13. Group 16 is the Oxygen Family.
14. Group 17 is the Halogen, salt families
15. Group 18 is the Noble Gases, and are very stable and not reactive.
I hope this helps. :)
A wave is a disturbance that carries energy from one place to another. Matter is NOT carried with the wave! A wave can move through matter (a medium). If it must have a medium, it is called a mechanical wave.

Question
A female spinach plant with flat (Ff) leaves is crossed with (pollination and fertilization occur) a male spinach plant with crinkly (ff) leaves. Explain wha
Explanation:
The location of reduction in an electrochemical cell is called the anode.
An electrochemical cell ( galvanic cell ) is generate electric energy from chemical reactions. In galvanic cell species ( for example zinc and zinc cations ) from one half-cell lose electrons ( oxidation ) and species from other half-cell ( for example copper and copper cations ) gain electrons ( reduction ). Electric current is generated due to the flow of electrons from the anode that undergoes an oxidation reaction to the cathode which has a reduction reaction in the circuit of an outer wire circuit.
