Question

the periodic table contains three types of elements: metals - hard, shiny elements that conduct heat and electricity. non - metals - poor conductors of heat and electricity. metalloids - have some properties of metals and some of nonmetals. instructions: in the periodic table below, label metals, nonmetals, and metalloids. classify the elements below as metals, nonmetals. 5) krypton (kr)

Explanation:

Metals are on the left - hand side and in the middle of the periodic table. Non - metals are on the right - hand side, and metalloids are along the staircase - like diagonal line separating metals and non - metals. Typically, elements like those in groups 1 and 2 are metals, noble gases are non - metals, and elements such as boron, silicon, etc. are metalloids.

Answer:

For the classification of elements in the periodic table:

• Metals: Elements on the left - hand side (Groups 1 and 2) and most in the middle (transition metals).
• Non - Metals: Elements on the far right - hand side, including noble gases (Group 18) and halogens (Group 17).
• Metalloids: Elements along the diagonal line starting from boron (B) to polonium (Po) such as boron, silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and polonium (Po).

For the specific element Krypton (Kr): Non - Metal. It is a noble gas in Group 18 and is a poor conductor of heat and electricity.
