Which element has similar properties to lithium explain?
Since sodium (Na) is in the same family as lithium and is just below it in the periodic table, sodium should be the most similar to lithium.
What element is will have the most similar physical and chemical properties to the element lithium Li )?
The elements in the first column of the Periodic Table (other than hydrogen) are known as Group 1A metals, or alkali metals. When you compare the chemical properties of these elements (lithium, sodium, potassium, rubidium, cesium, and francium), what you’ll notice is that they are all remarkably similar.
What elements have the same physical and chemical properties?
The answer is b. Elements in the same group have the same number of valence electrons and so interact with other elements in a similar way. They display similar physical and chemical properties. For example, the halogens (F, Cl, Br, I) all react similarly.
Why are the chemical properties of Na K and Rb similar?
They are the same because each has the same electron configuration.
How do you know chemical properties are similar?
Two different elements have similar chemical properties when they have the same number of valence electrons in their outermost energy level. Elements in the same column of the Periodic Table have similar chemical properties.
What elements have the same properties?
Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals.
What does oxygen share similar properties with?
Explanation: Oxygen is in group 16/VIA, which is called the chalcogens, and members of the same group have similar properties. Sulfur and selenium are the next two elements in the group, and they react with hydrogen gas (H2) in a manner similar to oxygen.
Does Na K and Mg have similar chemical properties?
Sodium and potassium share similar physical and chemical properties because they are in the same family or group called Alkali metals. Both will have the same valence electrons and they are both very reactive.
Which group 16 element has only unstable isotopes?
polonium
Which is the most active nonmetal?
Chlorine
What do mg K and Ca have in common?
Chemical Periods This means that their highest-energy electron is in the S-orbital shell. Potassium and calcium both appear next to each other in the fourth row of the periodic chart, making them period four elements. Like magnesium and sodium, their outer electrons are all in the S shell.
What do the elements Ca mg and be have in common?
The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure. Be, Mg and Ca are alkaline earth metals which are occupied the group-2 of the periodic table.
Is Xenon shiny or dull?
Xenon is a rare, odorless, colourless, tasteless, chamically unreactive gas.
How dangerous is Xenon?
Xenon Hazards Inhalation: This gas is inert and is classified as a simple asphyxiate. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death. Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue.
Why is solid calcium a good conductor of electricity?
Calcium is a good conductor of electricity because it has metallic bonding which allows the delocalized electrons (those from the outer shell) to flow freely from atom to atom, conducting electricity.
Are good conductors of heat and electricity?
Metals are elements that are good conductors of electric current and heat. They also tend to be shiny and bendable – like copper wire. Most metals are good thermal AND electrical conductors. Metals also generally have low specific heat (which means they heat up quickly).
What is a bad conductor of heat and electricity?
Tungsten is a metal which is a bad conductor of heat and electricity.
