How to break the header into blocks?

Question

BEM

I have this hat.

And the question is this.
The first block is header. This is clear.
What about the logo, phone number, social links and menu?
Are these header elements or separate blocks?
If blocks, then what is the correct name for them, provided that the logo and social links are duplicated in other places.

Answer 1

Personally, I would make 4 more blocks inside the .header block: logo, phone, social media and menu.
Something like this:

.header
    .header__logo
        .logo
    .header__phone
        .phone
    .header__social
        .social
            .social__link .social__link--instagram
            .social__link .social__link--vkontakte
            .social__link .social__link--facebook
    .header__menu
        .menu
            .menu__item .menu__item--active
            .menu__item
            .menu__item
