<prompt> Hlalosa hore na ke hobaneng ha likarolo tse ling li na le litšobotsi tse tšoanang.nan  <response>: Instruction in English: Explain why some elements have the same properties. . Response in English: Some elements have the same properties because they belong to the same group or family in the periodic table. The periodic table is arranged in such a way that elements with similar properties are placed in the same column. This is because the elements within the same group have the same number of valence electrons, which are the electrons in the outermost shell of an atom that are involved in chemical reactions. The number of valence electrons determines an elements chemical behavior, reactivity, and ability to bond with other elements. Consequently, elements within the same group can exhibit similar chemical and physical properties due to the similarity in their electron configuration. For example, elements in group 1, known as the alkali metals, are all highly reactive, and elements in group 18, known as the noble gases, are all inert. . Response in Sesotho: Lintho tse ling li na le thepa e tšoanang hobane ke tsa sehlopha se le seng kapa lelapa le le leng tafoleng ea periodic. Tafole ea periodic e hlophisitsoe ka tsela eo likarolo tse nang le thepa e tšoanang li behoang kholomong e le ngoe. Lebaka ke hore likarolo tse ka hara sehlopha se le seng li na le palo e lekanang ea lielektrone tsa valence, e leng lielektrone tse ka hara khetla e ka ntle ea athomo tse amehang tšebetsong ea likhemikhale. Palo ea li-elektronike tsa valence e khetholla boitšoaro ba likhemikhale tsa element, reactivity, le bokhoni ba ho ikopanya le likarolo tse ling. Ka lebaka leo, likarolo tse ka hara sehlopha se le seng li ka bontsa likhemikhale tse tšoanang le tsa mele ka lebaka la ho tšoana ha tlhophiso ea tsona ea elektronike. Mohlala, lielemente tse sehlopheng sa 1, tse tsejoang ka hore ke litšepe tsa alkali, kaofela li sebetsa haholo, me likarolo tse sehlopheng sa 18, tse tsejoang ka hore ke likhase tse ntle, kaofela ha li na letho.
