It is the atomic number of the element, which is <span>the number of protons in the nucleus of an atom that determines the chemical properties of an element. </span>
Answer:
C.5
Explanation:
A number of electrons present in valence shell of penultimate Shell represents the group of elements.
For s block elements: no.of group=number of valence shell electron.
p block elements: no. of group= 2 + 10 + number of valence electrons.
d block elements: no. of group= number(n-1)d electrons + number of electrons in nth shell.
Here, the differential electron is in p orbital hence, it belongs to p block
No. of group= 2+ 10 + 3=15 i.e 15th group or VA group.
Hydrogen is a
covalent bond. (A bond where one or more pairs of electrons are shared by two atoms)
I think its C not 100% sure tho
A evole like a pokemon does to its environment.
