Which elements do you expect to lose or gain electrons in their chemical reactions nitrogen iodine tungsten strontium gold?

Nitrogen can gain 3 electrons to form the nitride ion

Iodine gains 1 electron to form the iodide anion.

Tungsten loses electrons - variable number- it is a transition metal.

Strontium loses 2 electrons- it is in group 2

Gold loses electrons (note not very reactive)

Is strontium nitrate an electrolyte?

Most nitrate compounds are highly soluble in water, so adding strontium nitrate to water would create a large number of free ions in the water. These free ions could then act as charge carriers, making the water able to conduct current. Since adding strontium nitrate would make the water conductive, strontium nitrate is an electrolyte.

Some other strontium salts, such as strontium sulfide, wouldn't dissolve significantly in water, so they wouldn't create the free ions necessary to conduct current.

Are the properties of rubidium more similar to those of cesium or those of strontium?

Cesium. For non-transition elements such as rubidium, cesium, and strontium, the most chemically similar element to any other element is always one in the same column of the periodic table but in an adjacent row. Since strontium is not in the same column as rubidium but cesium is in the same column and an adjacent row, the answer follows. (This rule is sometimes true also for transition elements, but not always: For example, for elements in columns 8, 9, and 10, the most nearly chemically similar element is one in the same row and an adjacent column within this group, rather than one in the same column but an adjacent row.)

Why is Strontium more reactive than Calcium?

strontium is more reactive than calcium because it is more electropositive. valance electrons of strontium are farther away from the nucleus of strontiium atom than the valance electrons of calcium from nucleus of calcium atom. so the force exerted by the nucleus on the valence electron of strontium is lesser than that exerted by calcium. so the strontium atom can loose its valance electrons more easily. therefore strontium is more electropositive and more reactive than calcium.

Why is the first ionisation energy of strontium larger than the first ionisation energy of rubidium?

Because, as we know that when we go across the period of the periodic table, the number of shells remain the same but the number of electrons and protons increases. So, Rb having its atomic number as 37 and Sr as 38, Strontium has got more nuclear charge as well as more electrons. As a result the first ionisation energy required to remove one electron is more in Strontium than Rubidium.

How is a strontium atom different from a strontium ion?

A strontium atom differs from a strontium ion in that the atom has a greater number of electrons Explanation: Strontium has 2 valence electrons in its outer shell. It is easier to lose these 2 electrons than it is to gain 6 more electrons. Losing 2 electrons will give the strontium ion a charge of +2. Ions are charged atoms. An neutral atom has no charge because it has the same number of protons and electrons. An ion can have more or less electrons than an atom of the same element does. A strontium atom would have 2 more electrons than a strontium ion.

What is the difference in terms of electrical conductivity between liquid strontium chloride and liquid sulfur chloride?

Strontium Chloride is an ionic compound, means it's made up of positively charged strontium ions and negatively charged chloride ions arranged in a giant lattice. In the solid form, strontium chloride will not conduct electricity. This is because in the solid forms, the ions are not mobile, as they are fixed in place, in the lattice structure. Since the ions can't move a current cannot flow therefore it does not conduct.

In the liquid from (either molten or dissolved) strontium chloride will conduct electricity. This is because in the liquid form the ions are free to move. this means a current can flow.
