Atoms Around Us Molecules are groups of atoms bonded together in the same way that words are groups of letters. An A will always be an A no matter what word it is in. A sodium (Na) atom will always be a sodium atom no matter what compound it is in. While the atoms have different masses and organization for each element, they are all built with the same parts.

- Thanks. Obviously atomic number = no of protons = total number of electrons in an atom. Sodium 2,8,1 (1s1 2s2 2p6 3s1) has 13 electrons and is a group 1 element so has 1 valence electron (1 electron in outer shell). So 12 core and 1 valence.

What Is the Atomic Mass of Sodium? Quick Answer. Sodium is a metallic element on the periodic table with an atomic number of 11 and an atomic mass of 22.98 amu. This atomic mass is calculated by adding together the number of protons and neutrons present in the atom's nucleus. Sodium was discovered by Sir Humphrey Davy in 1807.

What is the formula for sodium nitride? #Na_3N#. Sodium is an element in group 1 of the periodic table. As such, it will form an electron by losing a single electron to form a #1+# ion: #Na^+#. Nitrogen is an element in group 5 of the periodic table. When it forms the nitride ion, it gains three electrons to form a #3-# ion: #N^(3-)#. In ionic compounds, the charges of constituent ions must balance. This can be achieved by having three sodium ions per nitride ion. Therefore, the formula of sodium nitride is #Na_3N#.

If A represents atomic mass and Z represents atomic number, which of the following describes an atom after a proton is emitted from its nucleus? The number of protons in the nucleus of an atom is called the atomic number. Atoms of the same element have the same atomic number. For sodium (Na) the atomic number is 11. All sodium atoms must have 11 protons in their nucleus. The atomic number therefore tells you what the element is (see the periodic table).

How many protons, electrons and neutrons does sodium have? Sodium, Na has: 11 protons (atomic number) 11 electrons (same as atomic number to even out the positive charge to make an overall neutral atom) 12 neutrons (atomic mass - atomic number) The correct answer is 11 protons, 10 neutrons, 11 electrons.

SO-DI-UM As we begin our exploration of the third period (row) of the periodic table, we find the element sodium (Na). Being in the first column, sodium is a member of the alkali metal family with potassium (K) and lithium (Li). Sodium's big claim to fame is that it's one of two elements in your table salt. When bonded to chlorine (Cl), the two elements make sodium chloride (NaCl).
