Three characteristics of metals are their good conductivity, malleability, and shiny appearance. Metals are good conductors of heat and electricity,...

Transition metals are able to put more than eight electrons in the shell that is one in from the outermost shell. Think about argon (Ar).

The transition metals are in Groups 3 through 12 and include iron, copper, nickel, gold, and silver. Most of these metals are hard and shiny solids. ... Except for mercury, the transition metals have high melting points and high densities. They are good conductors of heat and electric current, and are very malleable.

['In physical property metals contains lustrous surface and can polished. [00:07]', 'Metals are solid and heavy, even though sodium, potassium, magnesium, aluminium etc. are comparatively lighter metals. [00:16]', 'Metals are excellent conductor of warm and electricity. [02:40]', 'Melting points and boiling points of metals are very high. [03:19]']

Properties of P-Block Metals P-block metals have classic metal characteristics: they are shiny, they are good conductors of heat and electricity, and they lose electrons easily. Generally, these metals have high melting points and readily react with nonmetals to form ionic compounds.

['Have high melting points.', 'Have high boiling points.', 'Tend to be soluble in water.', 'Conduct electricity in liquid form and in aqueous solution.', 'Are usually hard and brittle solids.', 'Have high enthalpies of fusion.', 'Have high enthalpies if vaporization.']

The melting and boiling points are generally lower than transition metals but their electronegativity is higher, and they are softer than all the other metals. They are generally distinguished from metalloids. ... Poor metals follow the completion of each d-shell.

Transition metals are also high in density and very hard. ... Compared with the alkali metals in group 1 and the alkaline Earth metals in group 2, the transition metals are much less reactive. They don't react quickly with water or oxygen, which explains why they resist corrosion.

Transition metals. The transition elements are metals. They have high melting points and densities, and are strong and hard. They form coloured compounds and act as catalysts.

Group 1 metals produce hydrogen gas when reacting with water (pretty vigorously). In contrast, transition metals have higher melting points and much less reactive so do not reach as vigorously with water or oxygen.

Early transition metals are on the left side of the periodic table from group 3 to group 7. Late transition metals are on the right side of the d-block, from group 8 to 11 (and 12 if it is counted as transition metals).

Metals tend to be strong and conductive, and have high melting points. However, like nonmetals, their forms occur as a distinct combination of electrons, protons and neutrons. All elements, metal or otherwise, can change state or react.

Metals are the largest category of elements and they are characterized by their appearance: usually they possess a silvery shine, they are solid (except for mercury), they are malleable and they conduct electricity and heat. Transition metals are the elements that belong to the middle of the periodic table.

['It is a hard ferromagnetic, silver-white, lustrous, brittle element.', 'It is stable in air and does not react with water.', 'Like other metals, it can also be magnetized.', 'With dilute acids, it reacts slowly.', 'The metal melts at 1495 °C and boils at 2927 °C.']
