Answer: The simplest way to use the periodic table to identify an element is by looking for the element's name or elemental symbol. The periodic table can be used to identify an element by looking for the element's atomic number. The atomic number of an element is the number of protons found within the atoms of that element.
The six steps of the scientific are:
1. State the question
2. Conduct research
3. Create a hypothesis
4. Perform the experiment
5. Analyze the data
6. Conclusion
So D. would be the correct answer, even though communicating the results could possibly be a step if it's required.
Na and Cl would most likely form an ionic compound
Answer:966.45ml
Explanation:
Using Charles law.. V1/T1=V2/T2
V1=535ml
T1=-25+273
=248k
T2= 175+273=448k
V2=?
V2= V1*T2/T1
V2=535*448/248
V2=239680/248
V2=966.45ml
Answer:
As previously discussed, there is a connection between the number of protons in an element, the atomic number that distinguishes one element from another, and the number of electrons it has. In all electrically-neutral atoms, the number of electrons is the same as the number of protons. Each element, when electrically neutral, has a number of electrons equal to its atomic number.
