Answer:

The elements in each group have the same number of electrons in the outer orbital. those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.

Answer:

They have similar chemical properties!

Explanation:

A column of periodic table is called a group. Elements in a group have similar properties. Like group 1 elements, Lithium and Sodium are extremely reactive. They both fall under same group which is group 1.

They also have same number of valence electrons this is one of the reasons why they have similar chemical properties.

Provide one example of how life on Earth would not be possible without water based on its characteristics.
snow_lady [41]

Answer: ice is less dense than liquid water. If ice was more dense, Earth would freeze.

Explanation: There are many reasons why life on Earth depends on the characteristics of water. One could discuss hydrogen bonds and its role as a solvent, but the unusual property of water is is the change in density with change in temperature. Water is densest at 4 degC, which is why ice floats - it is less dense than cold water (it melts quickly in warm water, so density isn’t impotant at higher temperatures). Most liquids are less dense than the solid, frozen form. If this was the case with water, any ice that formed would sink, and sease would freeze from the bottom up. Furthermore, the lowest layers would be insulated and would not all melt in summer. Thus over time, the seas would become a thin layer of liquid water at best, over solid ice. Life could not develop without liquid seas. In addition, ice is reflective, reducing the amount of sunlight absorbed, further reducing temperatures. Without ocean circulation, polar areas would be even colder, and there would be no rain.

g Which of the following is TRUE for a system that is in dynamic equilibrium? Which of the following is TRUE for a system that i
Firdavs [7]

Answer:

none of the above

Explanation:

A system is said to have attained dynamic equilibrium when the forward and reverse reactions proceed at the same rate. That is;

Rate of forward reaction = Rate of reverse reaction

The implication of this is that the concentrations of reactants and products remain constant when dynamic equilibrium is attained in a system. This does not mean that the reactant and product concentrations become equal; it rather means that their concentrations do not significantly change once dynamic equilibrium has been attained.
