How many protons are in one atom of rubidium - 85?
There are 37 protons in one atom of rubidium-85.
When an atom gains an electron what charge does it have?
An atom that gains three electrons will become an ion with a 3- charge.
What is the largest atom in row 5?
It is the rubidium metal. it is in the first group.
What describes what happens when an atom becomes an ion with a two negative charge?
This atom gain two electrons and become an anion.
What kind of charge would a sodium atom have if it lost one electron?
Sodium become a cation (positive charge) - Na+.
How does an atom of rubidium-85 become a rubidium ion with a 1 charge?
An atom of rubidium-85 becomes a rubidium ion with a 1 charge by losing one electron. Since rubidium-85 has 37 protons and 37 electrons, losing one electron would result in the ion having 37 protons and 36 electrons, giving it a net charge of +1.
Is a rubidium larger or smaller than a neutral atom?
A rubidium atom is larger than a neutral atom because, when it loses an electron to become an ion, it loses an electron from the outermost shell, increasing the effective nuclear charge which attracts the remaining electrons closer to the nucleus, reducing the size of the ion compared to the atom.
What is the number of chlorine atoms needed to bond with rubidium?
1: RbCl (Rubidium has 1+ charge, and Chlorine has 1-)
What is the symbol for rubidium ion is?
Rb+
What is the formula for ionic compound for rubidium and sulfur?
The formula for the ionic compound formed between rubidium and sulfur is Rb2S. Rubidium is a group 1 element with a +1 charge, and sulfur is a group 16 element with a -2 charge. To balance the charges, two rubidium atoms are needed for every sulfur atom.
How many protons are in one atom of rubidium - 85?
There are 37 protons in one atom of rubidium-85.
When an atom gains an electron what charge does it have?
An atom that gains three electrons will become an ion with a 3- charge.
When a chlorine atom ionizes. what does its charge become?
When a chlorine atom ionizes, it gains one electron to become the chloride ion with a charge of -1.
What kind of charge does an atom have after losing an electron?
This atom become a cation (positive).
What is the formula for ionic compound formed between Rb and P?
The formula for the ionic compound formed between rubidium (Rb) and phosphorus (P) is Rb3P, because rubidium is a group 1 metal with a +1 charge and phosphorus is a group 15 nonmetal with a -3 charge. To balance the charges, you need three rubidium atoms for every one phosphorus atom.
Which neutral atom is isoelectronic with Rubidium?
krypton
