Since elements in group 1 only have 1 valence electron and elements in group 17 have 7 valence electrons, the one electron from the element in group 1 transfers to the group 17 element. That way, there are 8 valence electrons in this new bond, or a full outer energy level!

Ionicly

They do not share electrons. All of the electrons get attracted the the group 7 element and they stick together electrostaticly.

. If this same atom with 22 protons and 19 electrons were to gain 3 electrons, the net charge on the atom would be
frez [133]

Answer: No charge (0)

Explanation:

The atom has a proton of 22 and electron number of 19. This means the element has lost 3 electrons. Therefore, the net charge is +3.

So, if this atom gains 3 more electrons, the net charge would be zero (neutral).

The total number of electron would now be 22 which is the same as the proton number.

This implies the atom is now in an unreacted state or ground state.

A solution of silver chlorate reacts with a solution of lithium iodide.
Anettt [7]

Answer: Ag^+(aq)+I^-(aq)\rightarrow AgI(s)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:

AgClO_3(aq)+LiI(aq)\rightarrow AgI(s)+LiClO_3(aq)

The complete ionic equation is:

Ag^+(aq)+ClO_3^-(aq)+Li^+(aq)+I^-(aq)\rightarrow AgI(s)+Li^+(aq)+ClO_3^-(aq)

The ions which are present on both the sides of the equation are lithium and chlorate ions. and hence are not involved in net ionic equation.

Thus the net ionic equation is:

Ag^+(aq)+I^-(aq)\rightarrow AgI(s)

How does a sample of hydrogen at 10 °C compare to a sample of hydrogen at 350 K?
Andrej [43]

Answer: -

C. The hydrogen at 10 °C has slower-moving molecules than the sample at 350 K.

Explanation: -

The kinetic energy of gas molecules increase with the increase in the temperature of the gas. With the increase in kinetic energy, the gas molecules also move faster. Thus with the increase of temperature, the speed of the molecules increase.

Temperature of first hydrogen gas sample is 10 °C.

10 °C means 273+10 = 283 K

Thus first sample temperature = 283 K

The second sample temperature of the hydrogen gas  is 350 K.

Thus the temperature is increased.

So both the kinetic energy and speed of molecules is more for the hydrogen gas sample at 350 K.

Thus the hydrogen at 10 °C has slower-moving molecules than the sample at 350 K.

Hence the answer is C.
