Which of the following nonmetals exist as diatomic molecules at room temperature select all that apply?

Which of the following nonmetals exist as diatomic molecules at room temperature select all that apply?

Several of the nonmetals are gases in their elemental form. Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules (H2, N2, O2, F2, Cl2).

Does the metal in a binary ionic compound must have a very low ionization energy?

This is often possible in the case of a binary compound (one which contains only two elements), because formation of a binary ionic compound places quite severe restrictions on the elements involved. One element must be a metal and must have a very low ionization energy (see Figure 6.9. 1 for the IE of various metals).

What are the metals in the middle of the periodic table called?

The transition metals are found in the center of the main body of the Periodic Table. They are sometimes called heavy metals and are denser than alkali or alkaline earth metals.

Which of the following nonmetals is solid in its natural state?

Carbon is a solid non-metal element. Pure carbon can exist in very different forms. The most common two are diamond and graphite.

Do nonmetals gain or lose electrons?

Nonmetals, which are found in the right-hand region of the periodic table, have relatively large ionization energies and therefore tend to gain electrons.

What are the properties of nonmetals compared to metals?

Compared to metals, nonmetals display a highly variable range of properties, in terms of their atomic and chemical behavior. This is because nonmetals differ widely in interatomic and intermolecular bonding strengths. Most nonmetals tend to be gasses at standard temperatures and pressure and have low densities.

Why are there so many non metals in the world?

The fact that so many non-metals exist as liquids or gases means that non-metals generally have relatively low melting and boiling points under normal atmospheric conditions. In their solid-state, non-metals tend to be brittle. Therefore, they lack the malleability and ductility exhibited by metals.

Why are nonmetals not good conductors of electricity?

They are not good conductors of electricity or heat. They are very brittle in their solid form. They are not malleable or ductile. They generally have lower densities than metals. They generally have lower melting and boiling points than metals. The one exception to this is carbon. They have high ionization energies.

Where are the nonmetals on the periodic table?

The vast majority of elements — 87 in all — are metals, and these occupy the left, center, and part of the right-hand side of the periodic table. With the exception of hydrogen, placed in Group 1 above the alkali metals, the nonmetals fill a triangle-shaped space in the upper right corner of the periodic table.
