Hydrogen atom
has single electron in its valence shell. Which of the following option is
suitable for hydrogen atom to form molecule with another hydrogen atom?
a) to gain electron
b) to lose
electron
c) to share electron
d) none of these
The molecule of hydrogen is…..which formed by the sharing of electrons.
a) monoatomic
b) diatomic
c) triatomic
d) polyatomi
Explanation:Diatomic molecules (from Greek di- 'two') are molecules composed of only two atoms, of the same or different chemical elements. If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H 2) or oxygen ( O 2), then it is said to be homonuclear.
After sharing an electron, hydrogen gains stability by attaining electronic configuration like……..
a)argon
b) helium
c) neon
d) xenon
Shared pair of electrons in covalent bond is represented by……..
a) dot
b) cross
c) dash
d) all of these
The bond which formed by the sharing of electrons is called……..
a) ionic bond
b) covalent bond
c) dative bond
d) hydrogen bond
Which of the following elements make the covalent bonds?
a) metals & metals
b) non-metal & non-metal
c) metals & non-metals
d) all of these
