Does the f block element have 10 electrons?
If you tell me what an f block element is i can help you out. I aced chemistry last semester and ill probably be tutoring it next semester. are u referring to the families in the periodic table?
What are three halogens?
The halogens are: fluorine, chlorine, bromine, iodine, and astatine - although astatine only occurs in extremely minute quantities as part of the decay chain of some radioactive elements like uranium and thorium.
What is unique about element 89-112?
Elements 89-112, known as the actinide series, are part of the f-block in the periodic table. They have unique electron configurations due to the filling of the 5f orbitals. These elements also exhibit a variety of oxidation states and have applications in nuclear energy and research.
What do the four blocks of the periodic table have in common?
they're all cloud levels... i mean orbitals the first two rows are S cloud, the middle (transition metals) is the D cloud, the six rows on the left are the P cloud and the lanthanide series is F cloud
The f-block elements in period 7 are known as?
The f-block elements in period 7 are known as the actinides.
Which groups are the actinides?
The actinides are a group of elements in the periodic table that includes elements from atomic number 89 (actinium) to 103 (lawrencium). They are part of the f-block elements and are typically characterized by their radioactive properties. Some common actinides include uranium, plutonium, and thorium.
How many elements fit into each of the four blocks of the periodic table?
4: the s-block, the p-block, the d-block, and the f-block. there is an theoratical g-block but its not counted because its theoratical lol.
Why d and f block aliments called transition elements?
Transition elements may be defined as those elements which have partialy filled d and f subshells in atomic state so d and f block elements called transition elements.
Is f and d the center and bottom blocks of the periodic table?
D block elements are at the center of the periodic table; f block elements are at the bottom.
Why periodic table is divided in s p d and f block elements?
The s, p, d, f block realte to the filling of the outer shell orbitals. Group 1 and 2 are the s block. Groups 13-18 the p block, the transition metals the d block and the lanthanides and actinides the f block.
What are the f block elements known as?
inner transistion elements or rare earth elements
What is another name for the f block elements?
They are also called Lanthanides and they are Lanthanum, Cerium, Praesodymium, Neodymium, Promethium, Samarium, Europium, Gadolinium, Terbium, Dysprosium, Holmium, Erbium, Thulium, Ytterbium, Lutetium
The f-block elements in period 7 are known as the?
The f-block elements in period 7 are known as the actinides.
What do the lanthanide and actinides all have in common?
They are F-block elements
What element on the periodic table has ninety electrons?
A transition element of f-block Thorium has 90 electrons in natural state, it is a Radioactive element.
How many named elements are radioactive?
The very very bottom row of the 'f' block on the periodic table. ie. thorium protactinium uranium neptunium plutonium americium curium berkelium californium einsteinium fermium mendelevium nobelium lawrencium = 12
