What else can I help you with?
In what state are most elements in?
solid compounds. When pure still solid and mainly metallic
How many solids are in the periodic table?
There are 118 elements in the periodic table, and most of them exist in solid form at room temperature and pressure. About 80% of the elements are classified as metals, with most of them being solids.
How many atoms are humans made out of?
Humans are made up of trillions of atoms. The most common elements found in the human body are hydrogen, oxygen, carbon, and nitrogen, which make up the majority of our atoms.
What happens to atoms of most nonmetals when they react with other elements?
They tend to gain electrons when reacting with a metal. Metals generally are short of a full octet by 1 to 4 valence electrons. It is easier to drop 2 electrons than try to gain 6 electrons. The elements in group four can go either way, but the other metals will give up electrons, and non-metals will take them.
What particles make up elements and compounds?
Elements are made up of atoms, which consist of protons, neutrons, and electrons. Compounds are made up of molecules, which are formed when two or more different types of atoms are chemically bonded together.
Why do atoms of the most of the elements not exist independently?
There is sufficient chemical driving force to cause most elements to react with other elements into contact with which the elements come.
Do all elements have atoms and molecules?
All elements have atoms, but most do not form molecules.
What are most elements made of?
atoms
Which is capable of independent existence an atom or molecule?
Atoms of most elements are not able to exist independently. Atoms form molecules or ions aggregate in large numbers to form the matter that we can see. Molecule is capable of independent existence.
In which state of matter do most elements exist?
Most elements exist in the state of matter known as solids at room temperature and pressure. Some elements can also exist as liquids or gases depending on the conditions.
Does any element have different types of atoms?
Most elements have different types of atoms. These variations on an element's atoms are called isotopes and have different numbers of neutrons and thus different atomic masses. It is also possible to artificially create other isotopes of elements that do not exist "naturally," even for the few elements that normally have only one isotope (e.g. gold, arsenic, cobalt, aluminum, phosphorus).
Are all elements are composed of atoms that cannot be divided?
No. All atoms, except the most abundant isotope of hydrogen, can be divided into the subatomic particles protons, neutrons, and electrons. The most abundant hydrogen isotope does not have neutrons.
Why most elements not found in the free state in nature?
Most elements are sufficiently reactive so it can not exist in elemental form.
Can an atom exist without neutrons?
Yes. Most hydrogen atoms do not contain neutrons. All other atoms do.
What are atoms that collide frequently and move independently of one another are most likely in a what?
A fluid - liquid or gas.
Are most of the periodic table isotopes?
No most of them are not isotopes. Few elements exist as isotopes.
What phase of matter do most elements exist at room temperature?
solid...
