How many protons in a isotope of sodium with a mass number of 20?
All atoms of sodium contain 11 protons, since 11 is the atomic number of sodium.
Is salt made of atoms or molecules?
Salt crystals are formed from molecules, which are made of atoms. Table salt is sodium chloride, a compound whose molecules contain one atom of sodium and one atom of chlorine, joined by an ionic bond (sodium loses an electron and becomes a positive ion, chlorine gains an electron and becomes a negative ion).
Does hydrogen contain atoms?
Yes. All materials you will find on earth contain atoms.
Does sodium have electrons?
Yes. All atoms have electrons.
How many ions does sodium have?
All sodium atoms, whether or not they are ions have 11 protons.
Do sodium and chlorine have the same kind of subatomic particiles?
Yes: All atoms contain protons and electrons, and all except the atoms of hydrogen-1 also contain neutrons.
How many atoms are in the element NaCl?
In one molecule of NaCl there are two ions, Na+ and Cl-.
How many protons in a isotope of sodium with a mass number of 20?
All atoms of sodium contain 11 protons, since 11 is the atomic number of sodium.
Is sodium acetate organic or inorganic?
Sodium chloride contains only sodium and chlorine and so is inorganic. In order for a compound to be organic it must contain carbon and hydrogen.
Why sodium and silver are element while coal and soap are mixture?
All the atoms in sodium and silver contain the same number of protons in their nuclei, while this is not true for coal or soap.
Is salt made of atoms or molecules?
Salt crystals are formed from molecules, which are made of atoms. Table salt is sodium chloride, a compound whose molecules contain one atom of sodium and one atom of chlorine, joined by an ionic bond (sodium loses an electron and becomes a positive ion, chlorine gains an electron and becomes a negative ion).
Does hydrogen contain atoms?
Yes. All materials you will find on earth contain atoms.
Do all lithium atoms contain the same number of protons?
All the lithium atoms contain the same number of protons.
What do elements compounds and mixtures have in common?
The commonalities that elements, compounds, and mixtures all have in common is that they all contain atoms. Even though they all contain atoms, the number of atoms vary in each of them.
Sodium chloride,water, nitrogen,sodium,iron II sulphide, hydrogen, sulphide, silicon, chlorine which of the following has atoms in them?
All of the listed substances contain atoms, as atoms are the basic building blocks of matter. Sodium chloride (NaCl) is composed of sodium (Na) and chlorine (Cl) atoms. Water (H2O) is made up of hydrogen (H) and oxygen (O) atoms. Nitrogen (N2) is made up of two nitrogen atoms. Sodium (Na) is an element made up of sodium atoms. Iron II sulfide (FeS) is composed of iron (Fe) and sulfur (S) atoms. Hydrogen (H2) is made up of two hydrogen atoms. Sulfide (S) is an element made up of sulfur atoms. Silicon (Si) is an element made up of silicon atoms. Chlorine (Cl2) is composed of two chlorine atoms.
What cells in animal body contain sodium ion?
almost all but some cell does not contain sodium ion.
What do element and mixture have in common?
The commonalities that elements, compounds, and mixtures all have in common is that they all contain atoms. Even though they all contain atoms, the number of atoms vary in each of them.
