Which energy sublevel is being filled by the elements Rb to Sr?
The energy sublevel being filled by the elements Rb (rubidium) to Sr (strontium) is the 5s sublevel. These elements are in the fifth period of the periodic table, and in period 5, the s sublevel starts to fill up with electrons.
Rank from most to fewest valence electrons- Sb In Rb Xe?
Sb has 5 valence electrons, In has 3, Rb has 1 valence electron and Xe has 8. So in ranking, it would be, Xe, Sb, In, Rb.
How many electrons are in ruthenium?
Ruthenium has an atomic number of 44, which means it has 44 protons and, in a neutral atom, 44 electrons. Electrons are negatively charged subatomic particles that orbit the nucleus of an atom. Therefore, there are 44 electrons in a neutral atom of ruthenium.
Which one of the following is not isoelectronic with Kr a. As3 plus b. Se2- c. Rb plus d. Sr2 plus e. Br-?
c. Rb plus. Kr has 36 electrons, the same as Se2-, As3+, Sr2+, and Br-. Rb plus has 35 electrons, which is not isoelectronic with Kr.
Which has the smallest radius K Rb K Rb?
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
Which energy sublevel is being filled by the elements Rb to Sr?
The energy sublevel being filled by the elements Rb (rubidium) to Sr (strontium) is the 5s sublevel. These elements are in the fifth period of the periodic table, and in period 5, the s sublevel starts to fill up with electrons.
How many valence electrons do Rb have?
Rubidium has one valence electron in the 5s orbital.
How many electrons do Rb have?
Rubidium (Rb) has a +1 ion, will have the same electron configuration as krypton (Kr) because the +1 status means it has lost an electron. The configuration is written 1s22s22p63s23p64s23d104p6.
How many valence electrons does Rb have?
1 -apex
Which element completes the 3d sublevel?
This alkali metal is Rubidium Rb, having atomic no 37
What is the orbital diagram for Rb?
The orbital diagram for Rb (Rubidium) is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^1. This represents the distribution of electrons in the different energy levels and sublevels of the Rubidium atom.
Rank from most to fewest valence electrons- Sb In Rb Xe?
Sb has 5 valence electrons, In has 3, Rb has 1 valence electron and Xe has 8. So in ranking, it would be, Xe, Sb, In, Rb.
What is Rb's number of protons?
There is actually 37 Protons in Rb (Rubidium). Also there is the same number of protons as electrons. So 37 for protons and electrons. (: Your welcome little kid.
What is the noble gas configuration of rb?
[Kr] 5s1
How many valence electrons does Rb rubidium have?
Rubidium (Rb) has 1 valence electron. This is because it is in the first group (group 1) of the periodic table, which means it has 1 electron in its outermost shell.
How many electrons are in ruthenium?
Ruthenium has an atomic number of 44, which means it has 44 protons and, in a neutral atom, 44 electrons. Electrons are negatively charged subatomic particles that orbit the nucleus of an atom. Therefore, there are 44 electrons in a neutral atom of ruthenium.
Which one of the following is not isoelectronic with Kr a. As3 plus b. Se2- c. Rb plus d. Sr2 plus e. Br-?
c. Rb plus. Kr has 36 electrons, the same as Se2-, As3+, Sr2+, and Br-. Rb plus has 35 electrons, which is not isoelectronic with Kr.
