What can combine with other elements?

What can combine with other elements?

chemical compounds
When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl).

Which metals are so reactive that they are never found as uncombined elements in nature?

The alkali metals are so reactive that they are never found uncombined in nature. Common alkali metals are sodium and potassium.

What are three similar properties of alkali metals?

Alkali metals share many similar properties including:

• They are shiny, soft, metals.
• They are very reactive.
• They all have one valence electron in the outermost shell which they seek to lose in order to have a full outer shell.
• They are soft enough to be cut with a knife.

What is difference between elements and compounds?

Elements are substances that are pure in their nature and are composed of a single atom. Compounds are also pure substances that are composed of elements in definite proportions. Compounds can be broken down using chemical reactions. …

Why do atoms combine 11th?

An atom is the smallest particle of an element. It is so because the atoms in its outermost valence shell have a maximum of eight electrons and in order to complete this octet, they have a strong tendency to combine among themselves to acquire the stable electronic configuration of the nearest noble gas.

Which metal is generally found in native state?

Only two metals, gold and platinum, are found principally in their native state, and in both cases the native metals are the primary ore minerals. Silver, copper, iron, osmium, and several other metals also occur in the native state, and a few occurrences are large enough—and sufficiently rich—to be ore deposits.
