What has 78 protons and electrons?
What has 78 protons and electrons?
Platinum
Platinum is a chemical element with atomic number 78 which means there are 78 protons and 78 electrons in the atomic structure. The chemical symbol for Platinum is Pt. Since the number of electrons is responsible for the chemical behavior of atoms, the atomic number identifies the various chemical elements.
What is the name of the element with 79 protons?
element gold
The element gold. Gold is element 79 and its symbol is Au.
What is the correct element with its charge 80 protons 77 electrons?
The atomic number is the number of protons in an atom’s nucleus, so we can tell right away that an atom of mercury contains 80 protons. The mass number (201) is the total number of protons and neutrons.

What is the charge of beryllium?
+2
Beryllium has a positive charge. This element belongs to alkaline earth metals (group 2) and like the other elements in this group it has as an oxidation state of +2. Besides, beryllium has a tendency to lose electrons in order to attain a noble gas configuration. Thus, the charge on the beryllium ion will be +2.
How many electrons protons and neutrons are there in an atom of bromine 79?
Bromine-79 is composed of 35 protons, 44 neutrons, and 35 electrons.
How many protons neutrons and electrons are present in a single atom of selenium − 78?

What type of element is platinum?
platinum metals
Platinum is a silvery metallic chemical element, a member of the six transition elements in Group VIII of the periodic table known collectively as the platinum metals (ruthenium, rhodium, palladium, osmium, iridium, and platinum). Platinum has the symbol Pt, its atomic number is 78, and its atomic weight is 195.09.
How do you know what charge an element has?
There are four ways to find the charge of an element:
- Use the periodic table. The usual charge of an element is common to its group.
- Use a chart.
- For a single atom, the charge is the number of protons minus the number of electrons.
- Find the charge by balancing charge in a compound.
Why is it called platinum?
The name is derived from the Spanish ‘platina’, meaning little silver. A vertical column in the periodic table.
What is the symbol for the ion with 79 protons 76 electrons and 118 neutrons?
It is gold (Au) since it has 79 protons (the charge number of 79) and it has 118 neutrons (197 – 79 = 118). “gold-195” has 79 protons (or it wouldn’t be gold) but it has 116 neutrons.
What element has 79 protons and has 76 electrons?
79 protons corresponds to gold, Au. A gold atom has originally 79 electrons. (Must be the same number as proton to be electrically neutral) Since now it only has 76 electrons, it has lost 3 electrons.
What does 79 protons in a gold atom mean?
79 protons corresponds to gold, Au. A gold atom has originally 79 electrons. (Must be the same number as proton to be electrically neutral) Since now it only has 76 electrons, it has lost 3 electrons. It means now it has a state of +3.
