What element that has 18 electrons?
Palladium is the only element in the periodic table that has 18 electrons in its outermost shell.
What element has 18 electrons and a charge of?
A certain element forms an ion with 18 electrons and a charge of +2. … Recall that atoms have the same number of electrons as protons, and the atomic number of an atom is the number of protons it has. So, the atom in question is the atom whose atomic number is 20…..that's calcium (Ca).
What ion has a total of 18 electrons?
Argon has 18 protons and is a neutral atom, so it also has 18 electrons.
What atoms or ions have 18 electrons?
The element that forms an ion with 18 electrons and a charge of +2 is Ca (Calcium).
How many electrons does element 18 have?
So… for the element of ARGON, you already know that the atomic number tells you the number of electrons. That means there are 18 electrons in an argon atom.
What element has 18 protons and 18 neutrons?
Argon is a Group 0 element, on the Periodic Table, with 18 protons in the nucleus.
What cation with a 1+ charge has 18 electrons?
Sodium ion on right has 17 protons and 18 electrons, with a -1 overall charge.
Which of the following elements has 18 neutrons?
chlorine Some atoms of chlorine have 18 neutrons in their nuclei.
Which element has 18 electrons in each 2 anion?
Explanation: Table salt is NaCl , and thus the anion is Cl− , for which Z=17 . And if there are TWO chlorides, the NEUTRAL salt must contain a doubly charge charged cation. And since this cation has 18 electrons, for the parent atom Z=20 , i.e. the element is calcium.
What element has 18 as its atomic number?
