What way are lithium, sodium and potassium like other metals?

All these have one electron in the outermost shell.

They form unipositive ions.

They are good reducing agents.

They are soft metals.

They impart color to the flame.

The common name of the group is alkali metals

Explanation:

Lithium, sodium, potassium, rubidium, and cesium are all part of a group called the alkali metals. They are all soft metals in elemental form and they all react violently with water. They react so strongly because they all readily lose an electron to form the +1 cation very easily. n their pure forms, the alkali metals (lithium, sodium, potassium, rubidium, and cesium) are soft, shiny metals with low melting points. Alkali metals react readily with air and moisture. The alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
