Note the bold zigzag line" on the right-hand side of the periodic table on the last page. In general, metals (e. g. Mg.
AI, K, Na, Cu, Zn) are found to the left of this line, and nonmetals to the right (e. g. C, N, O, CI). A notable exception
is hydrogen, H. Although it's located far to the left, it is classified as a nonmetal. The vertical columns in the periodic
table are called Groups, while the horizontal rows are call periods.

35. In what group of the periodic table are the metals lithium (Li), sodium (Na) and potassium (K):
36. What is the charge of lithium and sodium ions?
37. Predict the charge of potassium ions. Explain your reasoning.

39. What is the charge of fluoride ions?
40. Predict the charge of chloride and bromide ions. Explain your reasoning.

i think the answer is 95 hope this

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.

the statements that apply here about binary star system are

"have stars that might appear to wobble"

"often have one star that is brighter than other"

a binary star is a star system consisting of two stars revolving around their common barycenter. systems of two or more stars are called multiple star systems.

the cover letter for a job search includes the skills one has for the particular job. including a cover letter is always a good idea, as it describes the ability to perform a task, and the employer can easily fetch the intention of the job you want to do.  

the cover letter is very important to be included in the job search document. hence, i strongly with the statement.
