Answer 1

hey mate !!

here is your answer !!

questions:-

which element comes after (right) lithium in the periodic table.

Beryllium elements comes after (right ) lithium in the periodic table .

the atomic weight of beryllium is 9.012.

the beryllium is denoted by the symbol of Be.

Beryllium is a alkaline earth metal.

Beryllium comes under second group and second period.

the no of electron is equal to 4. no of proton equal to 4.

no of neutron = no of atomic weight - no of atomic number

no of neutron = 9 - 4 = 5.

the no of neutron in beryllium is equal to 5.

in the modern periodic table .

some elements Name with symbol.

Hydrogen - H

Helium - He

Lithium - Li

Beryllium - Be

Boron - B

Carbon - C

Nitrogen - N

Oxygen - O

fluorine - F

Neon - N

Sodium - Na

magnesium - mg

Answer 2

Hi. Lithium is the third element in the periodic table. Thus, the element which comes after Lithium is the fourth element, ie, Beryllium. It's symbol is Be. Atomic number is 4, no. of protons = 4, no. of electrons = 4, no. of protons = 5, melting point = 278°C, boiling point = 2970°C and density = 1.84 g cm⁻³. Its period is 4 and it belongs to the family of Alkaline Earth metals. Hope it helps.
