An element A has two electrons in the outermost shell of its atom and combines with an element B having.

. Atomic number Electronic configuration Valence electrons 10 28 8 11 281 1 12 282 2 13 283 3 - Since. The compound when dissolved in water conducts electric current. In the picture here we can see the arrangement of electrons of an atom of lithium with two electrons in its inner shell and one more in its outer shell.

Outermost shell can not have more than 8 electrons and K-shell can have a maximum of two electrons. The maximum number of electrons that can be filled in the shell K L M N respectively are 2 8 18 32. A cation is a positively charged ion which occurs due to losing two.

If atomic number of an element is known arrangement of electrons in its atom can be written. Every atom aim to achieve stability by receiving electrons or giving their valence electrons in order to have a complete outermost shell of 2 duplet or 8 octet structure. A Will this electron form an ion.

Each electron shell has a certain number of electrons that it can hold before it fills up. Therefore a magnesium atom is 282 The magnesium ion Mg2 is formed when the magnesium atom loses the two electrons from its outer shell. An element has 2 electrons in its N shell i What is its atomic number.

According to Bohr Bury Scheme the electronic distribution in the first four shells is. What causes valence electrons. Ii State its position in periodic table iii Is it metal or non-metal.

In this case the atom X will easily give off its three valence electrons to another atoms thereby forming a trivalent positive ion X3 with a stable duplet or octet structure ie an outermost. An element A has two electrons in the outermost shell of its atom and combines with an element B having seven electrons in the outermost shell forming the compound AB 2The compound when dissolved in water conducts electric current. Iv State the name assigned to this group.

- The maximum number of electrons that can be accommodated in any shell is given by 2n2 where n is the shell number. A since the atom has two electrons in outermost M lshell this means that K and L shells are already filled. These are arranged 2 in the innermost n1 shell then 8 in the next n2 shell and the last two in the n3 shell.

The electronic configuration of a helium atom 1s2and which is a noble gas contains two valence electrons. A Since the atom has two electrons in outermost M-shell this means that K and F shells are already filled. 1 See answer Advertisement.

See full answer below. Hez 2 1s2. An element A has two electrons in the outermost shell of its atom and combines with an element B having seven electrons in the outermost shell forming the compound AB.

Helium atom has 2 electrons in its valence shell but its valency is not 2 Explain. Hence the valency of helium atom is zero. Was this answer helpful.

Giving reasons state the nature of chemical bond in the compound. If so what type. Shell Shell number n Maximum number of electrons K 1 2 L 2 8 M 3 18 - The electrons in the outermost shell are called valence elctrons.

Two electrons in its outermost and only shell two valence electrons. A valence electron is an electron in an outer shell of an atom that can participate in forming chemical bonds with other atoms. An atom with two electrons in his outermost shell will most likely form a cation.

Giving reasons state the nature of chemical bond in the compound. So as per this rule the 2 8 18 2 is the correct distribution and hence the suitable atomic number of the element with 2 outermost electrons would be 28182 30. Which Lewis dot diagram shows an atom that needs two more electrons in its outermost shell.

K2 L8 M18 N8. E If this atom joined another atom to form a molecule would the. In a single covalent bond both.

Is it a metal or a non-metal. An ionic bond where one atom essentially donates an electron to another forms when one atom becomes stable by losing its outer electrons and the other atoms become stable usually by filling its valence shell by gaining the electrons. Covalent bonds form when sharing atoms results in the highest stability.

It has no tendency to give or take electrons. The stability of an atom means complete outermost shell or octet this may be acquire by three ways 1- by gain of electrons 2- by loss of electrons and 3- by sharing of electronsBy bonding with. With the two electrons lost the electron.

Helium has 2 electrons in its outermost shell thereby completing duplet configuration as a result valency is zero. Helium atom has 2 electrons in its outermost shell and its duplet is complete. N- Shell will be 242 32.

As a result neutral helium will only have 2 electrons surrounding its nucleus. State its a Electronic configuration b Number of protons c Atomic number d Nature whether metal or non-metal e Valency f Name Answer. Is it most likely to participate in ionic bonds polar covalent bonds or non-polar covalent bonds.

An atom has 2 electrons in its outermost shell assume this shell holds a maximum of eight. Electrons are arranged in layers referred to as shells or energy levels. Therefore electronic configuration is 2 K 8 F 2 M b Number of protons Number of electrons 12 c Atomic.
